Abstract
Environmentally degradable molded or extruded articles comprising a blend of polyhydroxyalkanoate copolymer and an environmentally degradable thermoplastic polymer or copolymer are disclosed. Such compositions provide annealing cycle times to form molded or extruded articles that are less than annealing cycle times to form a molded or extruded article lacking the environmentally degradable thermoplastic polymer or copolymer.
