Poly(L-lactide-co-caprolactone)(85-15)[P(LLA-CL)(85-15)] was synthesized from high purity L-lactide and É-caprolactone using tin octoate as initiator by ring-opening polymerization, and characterized by infrared spectrum and 1H-NMR spectrum. The synthesized P(LLA-CL)(85-15) is a random copolymer. The influences of polymerization temperature, polymerization time, dosage of initiator and polymerization pressure on the weight average molecular weight and the polydispersity index of P(LLA-CL)(85-15) were investigated. The optimum preparation condi...
