Estudo da miscibilidade das misturas de PHB e PLA, com um PHB de alta polidispersividade

Abstract

In this work, the miscibility of a PHB formed by high and low molar mass fractions and a low molar mass PLA was studied. The extruded materials were analyzed by differential scanning calorimetry (DSC), dielectric spectroscopy (DS) and dynamic mechanical analysis (DMA). From these results, it was observed an unique behavior from the PHB fractions, and the partial miscibility of PLA onto low molar mass PHB.
