Abstract

Abstract: A series of poly(3-hydroxybutyrate-co-4-hydroxybutyrate)/ maletic anhydride (MA) blends was prepared via melt blending. The effect of MA content on the mechanical/thermal properties of the blends was studied. It indicated that with MA added, the mechanical properties of poly(3-hydroxybutyrate-co-4-hydroxybutyrate) were enhanced, thermal stability and processability were improved. The heat decompose temperatures increased by 19.31 ℃. Meanwhile, MA could improve the compatibility between 3-hydroxybutyrate and 4-hydroxybutyrate.

Key words: melt blending, poly（3-hydroxybutyrate-co-4-hydroxybutyrate）, maletic anhydrider, mechanical property
