## Abstract The sixโmembered lactide was polymerized using the ringโopening polymerization with lipase as a catalyst at a temperature between 80 and 130ยฐC in bulk to yield the corresponding polylactide with weightโaverage molecular weights of up to 126000. The most preferable conditions with respec

## Abstract In contrast to LLA, DLA is converted in toluene solution under mild reaction conditions (50โ70โยฐC) using Novozyme 435 (immobilized CALB) to form the corresponding polymer. The influence of several parameters, such as enzyme concentration, temperature and monomer concentration, on the po
## Abstract **Summary:** Poly(D,Lโlactide) with a molar mass of 10^5^ gโยทโmol^โ1^ and a yield over 90% was produced in 10 min by the ringโopening polymerization of D,Lโlactide under microwave irradiation with forward power of 255 W. A degradation of the poly(D,Lโlactide) was also induced by microwa
