ENVIRONMENTALLY DEGRADABLE POLYMERIC BLEND AND PROCESS FOR OBTAINING AN ENVIRONMENTALLY DEGRADABLE POLYMERIC BLEND

摘要

The present invention refers to an environmentally degradable polymeric blend,comprising biodegradable polymers defined by polyhydroxybutyrate (PHB) orcopolymers thereof and Polycaprolactone (PCL) and, optionally, at least oneadditive defined by a filler, nucleant, thermal stabilizer, processing aid,with the purpose of preparing an environmentally degradable polymeric blend.According to the production process described herein, the blend resulting fromthe mixture of the biodegradable polymers, PHB and PCL, and at least oneadditive, can be utilized in the manufacture of injected food packages,injected packages for cosmetics, tubes, technical pieces and several injectedproducts.
