Continuous Microwave-Irradiated Synthesis of Poly(D, L-Lactide)-co-Poly (Ethylene Glycol) Copolymer Under Atmosphere
Poly (D, L-lactide)-co-poly (ethylene glycol) copolymer (PELA) of Intrinsic viscosity 0.51 dL·g-1 had been prepared under continuous microwave-irradiation power of 90 W for 8 min at atmosphere. Effects of poly (ethylene glycol) ( PEG) content, polymerization time on intrinsic viscosity and yield of PELA had been discussed. Furthermore, temperature rising behavior in reactants system was studied through copolymerization under continuous microwave oven and domestic microwave oven. The results showed that temperature of reactants system evolved smoothly without step under continuous microwave irradiation, which occurred under intermittent microwave irradiation in domestic microwave oven.
