| 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. |
