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.
L'invention concerne des articles moulés ou extrudés dégradables contenant une composition copolymère C4C6 polyhydroxyalcanoate présentant une courte durée de cycles de recuit. Cette courte durée de cycles de recuit est obtenue pour des compositions présentant un pourcentage d'unités C6 compris entre 2 et 8 %. On obtient ainsi une durée souhaitable de cycles de recuit pour des articles moulés ou extrudés, en particulier pour des applicateurs de tampons.
