Abstract

Novel poly(3-hydroxyalkanoates), such as poly(3-hydroxybutyrate), and blends of these with other polymers are disclosed.
A novel process for producing these poly(3-hydroxyalkanoates) is also disclosed which entails polymerizing one or more .beta.-substituted-.beta.-propiolactone(s) under polymerization conditions in the substantial absence of water in the presence of an anionic initiator.
