| titleOfInvention | A kind of aliphatic-aromatic-polylactic-acid block copolymer |
| abstract | The present invention provides a kind of aliphatic aromatic polylactic-acid block copolymers to be made by following preparation method：A) aromatic binary carboxylic acid class compound, aliphatic dicarboxylic acid class compound, dibastic alcohol compound and monomer are reacted, obtains the hydroxy-end capped aliphatic aromatic copolyesters of molten state；The monomer includes multicomponent alcoholics compound, Polycarboxylic acids or polybasic carboxylic acid esters compound；B) the hydroxy-end capped aliphatic aromatic copolyesters of lactide and molten state is subjected to polymerisation, obtains aliphatic aromatic polylactic-acid block copolymer.There is aliphatic aromatic to be copolymerized ester structure, the aliphatic aromatic copolymerization ester structure is the branch of aliphatic aromatic polylactic-acid block copolymer, can improve the melt strength of aliphatic aromatic polylactic-acid block copolymer in the copolymer.In addition, the aliphatic aromatic polylactic-acid block copolymer has higher elongation at break. |
