摘要：
The present invention refers to a polymeric blend for the preparation of environmentally degradable materials, said blend comprising biodegradable polymers, polyhydroxybutyrate—PHB or copolymers thereof and poly(butylene adipate/butylene terephthalate) aliphatic-aromatic copolyester and at least one additive. The present invention further refers to the process for obtaining said blend, by applying the extrusion technique to obtain an adequate morphology in the distribution, dispersion and interaction of the polymers, so as to obtain compatible polymeric blends, allowing the granules of the produced polymeric blends to be utilized to manufacture several injection molded products.
