Open publisher page 1 citations

Abstract

Poly(D,L-lactic acid) was synthesized by direct polymerization of D,L-lactic acid using diphenyl ether as solvent in the presence of catalyst. The effects of catalyst, reaction temperature, reaction time on polymerization reaction were discussed. The product was characterized by M_v, IR and ~1HNMR.
