Abstract

"ARTIGOS MOLDADOS OU EXTRUDADOS COMPREENDENDO COPOLìMERO DE POLIIDROXIALCANOATO E UM POLìMERO TERMOPLáSTICO AMBIENTALMENTE DEGRADáVEL". São apresentados artigos moldados ou extrudados ambientalmente degradáveis, compreendendo uma mistura de copolímero de poliidroxialcanoato e um polímero ou copolímero termoplástico ambientalmente degradável. Essas composições oferecem tempos de ciclo de recozimento, para formar artigos moldados ou extrudados, que são menores que os tempos de ciclo de recozimento para formar um artigo moldado ou extrudado que não contém o polímero ou copolímero termoplástico ambientalmente degradável.
