## Abstract The sixβmembered lactide was polymerized using the ringβopening polymerization with lipase as a catalyst at a temperature between 80 and 130Β°C in bulk to yield the corresponding polylactide with weightβaverage molecular weights of up to 126000. The most preferable conditions with respec
Structurally characterized, chiral heterobimetallic yttrocene derivatives Li[Y(g 5 : g 1 -C 5 R 4 Si-Me 2 NCH 2 CH 2 OMe) 2 ] (R = Me, H) have been shown to be active in the controlled ring-opening polymerization of L-lactide to give poly(L-lactide)s with high molecular weights and moderately narrow
Zn(OAc) 2 β’2H 2 O is found to be an effective bulk polymerization catalyst for the ring-opening polymerization of rac-lactide, l-lactide, -caprolactone and β¦-valerolactone. The propensity of polymerizations can be enhanced by performing them in the presence of appropriate amounts of different alcoho
