| Abstract: | Biodegradable poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBH) was prepared as binary blends with amorphous poly(vinyl acetate) (PVAc) by melt blending method. The effect of PVAc contents on miscibility, isothermal crystallization kinetics, and rheological and mechanical properties of the blends was investigated. The single glass transition temperature of PHBH/PVAc blends revealed that PHBH and PVAc were miscible. The addition of PVAc increased the viscoelasticity of PHBH melt. The PVAc inhibited crystallization and reduced the crystallinity of PHBH. It was found that PVAc reduced isothermal crystallization rate, but did change crystallization mechanism. The most intriguing result was that prominent increases of 44 times was achieved in elongation at break of blend with 30 mass% PVAc compared to neat PHBH. Meanwhile, the modulus and yield strength did not deteriorate significantly. The unusual combination of good stiffness, toughness, and melt viscoelasticity helps degradable polymer systems meet the performance requirements of more industrial applications.
