Abstract
Environmentally degradable molded or extruded articles comprising a polyhydroxyalkanoate C4C6 copolymer composition having short annealing cycle times are provided. Such short annealing cycle times are achieved by compositions having a percentage of C6 units of 2-8%. Desirable annealing cycle times are obtained for molded or extruded articles, particularly for tampon applicators.
