| titleOfInvention | A kind of biodegradable segmented copolymer and preparation method thereof |
| abstract | The present invention discloses a kind of biodegradable segmented copolymer and preparation method thereof, the biodegradable segmented copolymer is chemically reacted including three steps, hydroxyl telechelic polyester intermediate is first generated by binary acid and diol reaction, it reacts to obtain polyester-polylactic acid triblock copolymer with lactide again, finally carries out chain extension using chain extender and obtain segmented copolymer.Raw material sources of the present invention are wide, and reaction condition is easily controllable, easy to operate, are suitable for industrialized production.This analog copolymer had not only had good biodegradability properties energy, excellent thermodynamic property and the processing performance of aliphatic polyester but also the brittleness for improving PLA, was high value added product, had broad application prospects in packaging material and medical article field. |
