Abstract
A polymer composition is disclosed which includes at least a first biodegradable copolymer. This first biodegradable copolymer is itself made up of: (1) from about 55 to about 99.5 mole percent monomer residues of 3-hydroxybutyrate, (2) monomer residues of a secondary monomer selected from the group consisting of 4-hydroxybutyrate, 3-hydroxyvalerate, 4-hydroxyvalerate, and 5-hydroxyvalerate, and (3) monomer residues of a tertiary monomer selected from the group consisting of hydroxyalkanoate monomers having from 6 to 22 carbon atoms.
