Abstract
Patente de Invenção: "MéTODOS PARA A PREPARAçãO DE COMPOSIçõES BIODEGRADáVEIS MACIAS E ELáSTICAS DE COPOLìMERO DE POLIHIDROXIALCANOATO E PRODUTOS POLIMéRICOS COMPREENDENDO ESTAS COMPOSIçõES". A invenção refere-se aos produtos poliméricos macios e elásticos são obtidos por estiramento de uma composição compreendendo um copolímero biodegradável de polihidroxialcanoato compreendendo pelo menos duas unidades monoméricas aleatoriamente repetitivas. A primeira unidade monomérica aleatoriamente repetitiva tem a estrutura (1), onde R^ 1^ é H ou C1 ou C2 alquila e n é 1 ou 2. A segunda unidade monomérica aleatoriamente repetitiva é diferente da primeira unidade monomérica aleatoriamente repetitiva e tem a estrutura (11), em que m varia de 2 a cerca de 9. Pelo menos cerca de 70% em moL do copolímero compreende unidades monoméricas aleatoriamente repetitivas tendo a estrutura da primeira unidade monomérica aleatoriamente repetitiva de fórmula (1). Os produtos apresentam combinações vantajosas de maciez e elasticidade enquanto mantendo a resistência mecânica.
