Abstract (en)
[origin: WO0130893A1] Soft and elastic polymer products are obtained by stretching a composition comprising a biodegradable polyhydroxyalkanoate copolymer comprising at least two randomly repeating monomer units. The first randomly repeating monomer unit has structure (I), wherein R<1> is H, or C1 or C2 alkyl, and n is 1 or 2. The second randomly repeating monomer unit is different from the first randomly repeating monomer unit and has structure (II), wherein m is 2 to about 9. At least about 70 mole % of the copolymer comprises randomly repeating monomer units having the structure of the first randomly repeating monomer unit (I). The products exhibit advantageous combinations of softness and elasticity while maintaining strength.
