Reseach on the Crystallization Behavior of PP-TPEE Blends
ZHOU Deng-fei, JIANG Jia-li, WU Xiao-hua, QIAN Yang, QIN Yan-fen, WANG Xiu-hua* (Textile Fiber Materials and Processing Technology Local Joint Engineering Laboratory of the National,Zhejiang Sci-Tech University, Hangzhou 310018, Zhejiang, China) Abstract: In this paper, polypropylene-g-glycidylmethacrylate (PP-g-GMA) was used as the compatilizer for polypropylene-thermal polyester elastomer (PP-TPEE) blends, the crystallization behavior of blends was investigated by X-ray diffracmeter(XRD) and differential scanning calorimeter(DSC). The result of XRD showed that the addition of TPEE and PP-g-GMA changed the crystal facet beter of PP, increased crystal plane spacing. The result of DSC showed that the addition of TPEE increased the heat crystallization temperature of the blend, decreased the crystallinity. As the increase of the content of PP-g-GMA, the crystallinity of the blend decreased further. The heat crystallization temperature of pure PP and PP-TPEE blends were gradually decreased with the increase of DSC cooling rate. Key words: polypropylene, thermal polyester elastomer, blending, crystallization, behavior
