- PolyglycolidePGA-polylactidePLA muliblock copolymer and method of synthesis of the same

摘要

In the manufacturing method of a multi-block copolymer, the step of preparing a polylactide (PLA) oligomer by ring-opening polymerization of L-lactide, and glycolide at the sock end of the polylactide (PLA) oligomer ( glycolide) by ring-opening polymerization to prepare a triblock copolymer of a polyglycolide (PGA) block-polylactide (PLA) block-polyglycolide (PGA) block having a hydroxyl group (-OH) Step, and coupling to the urethane reaction of a diisocynate (diisocynate) to at least any one of the triblock copolymer socks end, may include the step of preparing a multi-block copolymer.
