| titleOfInvention | Polyglycolide(PGA)-polylactide(PLA) muliblock copolymer and method of synthesis of the same |
| abstract | In the method for preparing a multi-block copolymer, the steps of preparing a polylactide (PLA) oligomer by ring-opening polymerization of L-lactide, glycolide ( glycolide) to prepare a triblock copolymer of polyglycolide (PGA) block-polylactide (PLA) block-polyglycolide (PGA) block having both ends of a hydroxyl group (-OH) by ring-opening polymerization Step, and coupling to at least one of both ends of the triblock copolymer by a urethane reaction of diisocyanate (diisocynate), it may include the step of preparing a multiblock copolymer. |
