The thermal and mechanical properties of hyperbranched poly(ester-amide)/polypropylene blends

摘要：

Hyperbranched poly(ester-amide) and polypropylene blends were prepared by melt mixing. The thermal and mechanical properties of the blends were characterized by dynamic mechanical thermal analysis (DMA), thermogravimetric analysis(TGA) and tensile testing. The results from thermal analysis indicated that the thermal stability of the blends was obviously improved, in comparison with pure polypropylene.The investigation on the mechanical properties showed that the tensile strength could be obviously increased by adding 5wt％ (by weight) hyperbranched poly(ester-amide) to the polypropylene matrix. The DMA results showed that the glass transition temperature decreased when the PS2550 content was higher.
