| titleOfInvention | A kind of aliphatic aromatic PLA random copolymer and preparation method thereof |
| abstract | The present invention provides a kind of aliphatic aromatic PLA random copolymer, has structure shown in Formulas I.Aliphatic segment and aromatic series segment are included in aliphatic aromatic PLA random copolymer provided by the invention with structure shown in Formulas I, they are in random distribution, improve the mechanical property of aliphatic aromatic PLA random copolymer.Test result indicates that：The elongation at break of aliphatic aromatic PLA random copolymer provided by the invention is 220%~550%.Present invention also offers a kind of preparation method of aliphatic aromatic PLA random copolymer：Only need to be by both-end carboxyl lactic acid, aromatic binary carboxylic acid class compound, aliphatic dicarboxylic acid class compound and dibastic alcohol compound is esterified and polycondensation reaction can be prepared by.This method technique is simple, and reaction condition is gentle, beneficial to industrialized production. |
