Dibutyltindimethoxide with Triphenylphosphine is found to be efficient initiators for ring opening polymerization of polylactide. The polymerization in case of dibutyltindimethoxide/ triphenylphosphine was carried out at 130°C for 40 hr. The monomer has been recrystallized 3 times with dry toluene to removes the meso compounds, which absorbs the moisture and effect polymerization reaction. Monomer to initiator ratio is having very significant role in polymerization reactions and its value ranging from 500-5000. The monomer conversion calculated by FTIR analysis of reaction product indicates that polylactide has been formed. The average molecular weight has been calculated by using Gel permeation chromatography.
