COMPOSITION FOR PREPARING A DEGRADABLE POLYOL POLYESTER, PROCESS FOR OBTAINING A POLYOL POLYESTER, AN ELASTOMER, FOAMS, PAINTS AND ADHESIVES, AND A DEGRADABLE POLYOL POLYESTER FOAM

摘要

The present invention refers to a polymeric blend for the preparation ofenvironmentally degradable materials, said blend comprising biodegradablepolymers, polyhydroxybutyrate - PHB or copolymers thereof and poly (butyleneadipate/butylene terephthalate) aliphatic-aromatic copolyester and at leastone additive. The present invention further refers to the process forobtaining said blend, by applying the extrusion technique to obtain anadequate morphology in the distribution, dispersion and interaction of thepolymers, so as to obtain compatible polymeric blends, allowing the granulesof the produced polymeric blends to be utilized to manufacture severalinjection molded products.
