Abstract:
A polymer product, obtained by stretching a composition characterized by a biodegradable polyhydroxyalkanoate copolymer comprising at least two randomly repeating monomer units, wherein the first randomly repeating monomer unit has the structure (I): wherein R1 is H, or C1 or C2 alkyl, and n is 1 or 2, and the second randomly repeating monomer unit has the structures (II): wherein R2 is a C3-C19 alkenyl, and wherein at least 70 mole % of the copolymer comprises randomly meeting monomer units having the structure of the first randomly repeating monomer unit (I); wherein the product is obtained by stretching the composition at a temperature above the glass transition temperature Tg of the composition and below the melting temperature Tm of the composition.
