## Abstract Triphenyltin methoxide (Ph~3~SnOMe) and diphenyltin dimethoxide (Ph~2~Sn(OMe)~2~)‐initiated polymerizations of β‐(__R__,__S__)‐butyrolactone were conducted in bulk at 50 and 75°C. The low catalytic reactivity of the initiator prevented lower temperatures. The stereosequences of the isol

In this study, we have prepared poly([ R,S ] -b-hydroxybutyrate) (P( [ R,S ] -b-HB) or PHB) from [ R,S ] -b-butyrolactone ( [ R,S ] -b-BL), using diþ erent aluminoxane catalyst systems (triethylaluminium/water, triisobutylaluminium/water, trioctylaluminium/water and tetraisobutyldialuminoxane/water)
