Abstract
"PRODUTOS DE POLìMERO COMPREENDENDO COMPOSIçõES DE COPOLìMERO DE POLIHIDROXIALCANOATO BIODEGRADáVEIS ELáSTICAS E MACIAS E MéTODOS PARA PREPARAçãO DE TAIS PRODUTOS DE POLìMEROS". Produtos de polímero elásticos e macios são obtidos alongando-se uma composição compreendendo um copolímero de polihidroxialcanoato biodegradável compreendendo pelo menos duas unidades de monómero aleatoriamente repetidas. A primeira unidade de monómero aleatoriamente repetida tem a estrutura (I), em que R^ 1^ é H, ou C1 ou C2 alquila, e n é 1 ou 2. A segunda unidade de monómero aleatoriamente repetida tem a estrutura (II), em que R^ 2^ é uma C3-C19 alquila ou C3-C19 alquenila. Pelo menos 70 % em mol do copolímero compreende unidades de monómero aleatoriamente repetidas tendo a estrutura da primeira unidade de monómero aleatoriamente repetida (I). Os produtos exibem combinações vantajosas de maciez e elasticidade ao mesmo tempo que mantendo a resistência.
