The six‐membered lactide was polymerized using the ring‐opening polymerization with lipase as a catalyst at a temperature between 80 and 130°C in bulk to yield the corresponding polylactide with weight‐average molecular weights of up to 126000. The most preferable conditions with respect to the molecular weight of the polylactide are the bulk polymerization using lipase PS at a temperature of 100°C. The D , L ‐lactide gave higher molecular weight compared to the D , D ‐ and L , L ‐lactide.
