Abstract

Compositions of high molecular weight poly(hydroxy acid) polymer having good thermal stability and a weight average molecular weight of >100,000 by GPC. The compositions include one or more chain-terminator compounds/impurities which may be incorporated into the polymer and rendered harmless by the presence of appropriate amounts of bi-functional and multi-functional polymerization initiators, processes of preparing the polymer, and uses of the polymer to provide containers and polymer films or film-derived packages prepared therefrom.
