N2 - Silica was modified by KH-550 and hyperbranched poly (amine-ester) (HBP) and PVC/SiO2 composite was prepared by melt-blending method. The structure and properties of the composites were characterized by means of SEM and mechanical properties tests etc.. The results show that addition of nano SiO2 improves the mechanical properties of PVC, and the reinforcing and toughening effect are the best when the content of nano SiO2 is 1%. The TEM photograph appears that nano SiO2 modified with hyperbranched poly (amine-ester) are distributed in PVC more homogeneously, so the mechanical properties of PVC/SiO2-HBP were the highest. Compared with PVC, the tensile strength, elongation at break, impact strength and flexural modulus of PVC/SiO2-HBP composite is increased by 24.68%, 15.73%, 4.07% and 184.84% respectively. The processing properties of the composite are also improved efficiently.
