This invention relates to binary blends of cellulose esters and aliphatic-aromatic copolyesters, cellulose esters and aliphatic polyesters as well as ternary blends of cellulose esters and/or aliphatic polyesters and/or aliphatic-aromatic copolyesters and/or polymeric compounds as well as fibers, molded objects, and films prepared therefrom.

Aliphatic aromatic copolyesters

Aliphatic-aromatic copolyesters and cellulose ester/polymer blends

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.

Biodegradable poly (3-Hydroxyalkanoate) compositions and blends

This invention relates to binary blends of cellulose esters and aliphatic-aromatic copolyesters, cellulose esters and aliphatic polyesters as well as ternary blends of cellulose esters and/or aliphatic polyesters and/or aliphatic aromatic copolyesters and/or polymeric compounds as well as fibers, molded objects, and films prepared therefrom.
