Effect of various added compatibilizers on the crystalline structure of polypropylene homopolymer/polybutylene terephthalate and polypropylene copolymer/polybutylene terephthalate polymer blends

摘要

Blends of semicrystalline isotactic polypropylene homopolymer and polypropylene copolymer with polybutylene terephthalate with different compatibilizers [i.e., styrene acrylonitrile, Surlyn, styrene- ethylene- butadiene styrene (SEBS), block copolymer and SEBS block copolymer grafted with maleic anhydride] were prepared by melt blending. Wide angle-X-ray scattering patterns of injection moldings were obtained. The crystallinity index and d-spacing were calculated with different concentrations of different compatibilizers. X-ray results in the structural investigation of the compatibilized blends correlated well with the different compatibilizer concentrations. (C) 2002 Wiley Periodicals, Inc. [References: 5]
