Poly(3-hydroxybutyrate)-based copolymers and blends: Influence of a second component on crystallization and thermal behavior

The thermal properties and the crystallization process of poly(3-hydroxybutyrate) (P3HB) and its copolymers, in the presence of other polymers were analyzed. The blends of P3HB and the copolymers with atactic poly(3-hydroxybutyrate), poly(vinyl acetate), poly(methylene oxide), poly(ethylene oxide), poly(methyl methacrylate) were considered. The influence of miscibility and composition on solidification kinetics and crystal structure was also discussed.
