Abstract:
Lactide一glycolide copolymerization with stannous octanoate as an initiator and dedecanolas regulator was carried out.The effect of reaction condition such as reaction time,temperature, initiatorconcentration, regulator and monomer ratbonpolymerization conversion,molecular weight and its distrbu-tion were investigated.The obtained results show that the finest reaction condition are initiator 0. 075%,ternperature 170℃ and reaction time 6hr.At this reaction condition,both molecular weight and polymer-ization conversion obtained are vecy high.
