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.Invention Patent: "METHODS FOR THE PREPARATION OF SOFT AND ELASTIC BIODEGRADABLE COMPOSITIONS OF POLYHYDROXYALCANOATE AND POLYMERIC PRODUCTS UNDERSTANDING THESE COMPOSITIONS". The invention relates to soft and elastic polymeric products are obtained by drawing a composition comprising a biodegradable polyhydroxyalkanoate copolymer comprising at least two randomly repetitive monomer units. The first randomly repetitive monomeric unit has structure (1), where R ^ 1 ^ is H or C1 or C2 alkyl and n is 1 or 2. The second randomly repetitive monomeric unit is different from the first randomly repetitive monomeric unit and has the structure ( 11), where m ranges from 2 to about 9. At least about 70% by moL of the copolymer comprises randomly repetitive monomer units having the structure of the first randomly repetitive monomer unit of formula (1). The products have advantageous combinations of softness and elasticity while maintaining mechanical strength.
