BACKGROUND
Technical Field

The present disclosure relates to an additive for plastic materials. More particularly, the present disclosure relates to a biodegradable plasticizer.

Description of Related Art

In order to solve the environmental problems brought on by plastic products, biodegradable plastics, such as polylactic acid (PLA), poly(butylene succinate) (PBS) and poly(butylene adipate-co-terephthalate) (PBAT), have already been developed. However, properties of this type of plastics are still not as good as petroleum-based plastics. For example, polylactic acid has excellent rigidity and high transparency, but lacks enough durability, heat resistance, impact resistance, flexibility and airtightness, which limits the applications of polylactic acid.

To deal with problems in properties, textures and costs of biodegradable plastics, conventional biodegradable additives can be added to change the flexibility and durability of biodegradable plastics. However, the enhancement of biodegradation in properties of biodegradable plastics made by adding conventional additives is still insufficient. Also, the conventional additives are likely to release and have higher cost, so there has a lot of improvements for the conventional additives. Furthermore, the conditions for degradation of biodegradable plastics are tough. For example, plastic products made of polylactic acid can completely degrade into carbon dioxide and water only under particular environmental conditions for a sufficient time, and then enter the cycle without harming the natural environment. However, it is pretty difficult for plastic products of polylactic acid naturally and completely degrading in a typical environment. In this regard, the important trend for future is to develop an additive, which can enhance the degradation rate to facilitate biodegradable plastics quickly degrading and entering the natural environment.

If the central structure is the benzene derivative, the position of the amine group and the position of the carboxyl group can be adjacent to each other (ortho) or not adjacent (meta or para) on the benzene derivative.

The amine group can be a functional group of —NH2, —NHR, or —NR2. Moreover, the amine group can be a primary amine, a secondary amine, a tertiary amine or a quaternary ammonium cation. Furthermore, a hydroxyl group can be substituted for the amine group of the first connecting structure. When the side-chain structure is connected to the hydroxyl group, the connection therebetween can be split through hydrolysis reaction, so that it is favorable for enhancing the biodegradability of the plasticizer.

When the molecule of the plasticizer includes two connecting structures, the two connecting structures are respectively the first connecting structure and the second connecting structure. Moreover, the molecule of the plasticizer can include three connecting structures, which are respectively the first connecting structure, the second connecting structure and a third connecting structure. The third connecting structure can be the residue of the amino acid. For example, the amine group of the residue from lysine can be taken as the third connecting structure, or the carboxyl group of the residue from aspartate can be taken as the third connecting structure. Further, the molecule of the plasticizer can include four connecting structures, which are respectively the first connecting structure, the second connecting structure, the third connecting structure and a fourth connecting structure. The third connecting structure and the fourth connecting structure can be the same functional groups, such as the binary amine groups of the residues from arginine, or can be different functional groups.

Moreover, the side-chain structure can be formed by polymerization of the monomers selected from the group consisting of ethylene glycol, polyethylene glycol, propylene glycol and polypropylene glycol. The side-chain structure is formed by polymerization of the abovementioned monomers, the required molecular weight of the plasticizer can be controlled, and the hydrophilicity and hydrophobicity of the plasticizer are properly adjusted, so that it is favorable for the plasticizer performing the superior characteristics and enhancing the compatibility of the plasticizer mixing with the plastic.

The side-chain structure is connected to at least one of the first connecting structure and the second connecting structure, that is, the central structure is connected to the side-chain structure through the first connecting structure and/or the second connecting structure by a method of esterification, dehydration or peptide synthesis.

When the side-chain structure is connected to the amine group, an amide bond is formed, so that it is favorable for enhancing the efficiency of the plasticizer degraded by the enzyme, and further improving the biodegradability of the plasticizer. Moreover, when the side-chain structure is connected to the carboxyl group, an ester bond is formed. Furthermore, when the side-chain structure is connected to the hydroxyl group, an ether bond is formed.

The polar functional group is arranged according to different requirements, so that it is favorable for enhancing the hydrophilicity of the plasticizer and the compatibility between the plasticizer and the plastic, which helps the plasticizer mix with the plastic.

When a number of carbon atoms of the side-chain structure which is connected to the amine group is nNC, and a number of carbon atoms of the side-chain structure which is connected to the carboxyl group is nOC, the following condition is satisfied: 0≤nNC/(nNC+nOC)≤1.00, wherein each of nNC and nOC is 0 or positive integer, but nNC and nOC are not 0 at the same time.

The carbon atoms or the oxygen atoms in the polar functional group are not included as calculating nNC, nNO, nOC, nOO, nO′C and nO′O. nO′C is taken as nOC and nO′O is taken as nOO during calculation.

When the molecular weight of the plasticizer is MwP, the following condition is satisfied: 450 Dalton≤MwP. As the molecular weight of the plasticizer is larger, it is more difficult for the plasticizer to pass through the cell membrane, so that it is favorable for preventing the plasticizer directly passing through the cell membrane into the cell. Moreover, the following conditions can be satisfied: MwP≤2000 Dalton; 475 Dalton≤MwP≤1000 Dalton; 500 Dalton≤MwP; 525 Dalton≤MwP; 550 Dalton≤MwP; or 600 Daltons≤MwP≤1500 Dalton.

Each of the central structures is connected to at least one of the connecting structures.

According to the present disclosure, the biodegradable plasticizer is developed by investigating a novel molecular structure. The plasticizer has the abilities of improving the plastic texture, meeting the requirements for widespread applications, and further enhancing the degradation and cycle of the plastic. The plasticizer includes the first connecting structure and the second connecting structure, includes the benzene derivative and/or the amino acid as the central structure, and is grafted with the side-chain structure of the chain with multiple carbon atoms. The plasticizer can further include the polar functional group to adjust the hydrophilicity and hydrophobicity of the plasticizer. The plasticizer, which reaches desire durability, heat resistance, impact resistance and flexibility, and is harmless to human body, hard to release and low-cost, is developed to meet the target of high biodegradability.

The foregoing description, for purpose of explanation, has been described with reference to specific embodiments and examples. It is to be noted that Tables show different data of the different examples; however, the data of the different examples are obtained from experiments. The embodiments and examples were chosen and described in order to best explain the principles of the disclosure and its practical applications, to thereby enable others skilled in the art to best utilize the disclosure and various embodiments or examples with various modifications as are suited to the particular use contemplated. The embodiments and examples depicted above and the appended drawings are exemplary and are not intended to be exhaustive or to limit the scope of the present disclosure to the precise forms disclosed. Many modifications and variations are possible in view of the above teachings.
