| 英文摘要 | Blends of sPS/iPP of various compositions from 55/45 to 82/18 were prepared with a novel catalyst by polymerization. Crystal forms, crystallinity and melting behavior of sPS/iPP blends have been studied by FT-IR spectroscopy, XRD and DSC. The results obtained show that the polymerization blending and the-processing at 290degreesC are favorable for formation of alpha-form crystals in, neat sPS and in sPS/iPP blends. Melting points (T-m) and crystallinity of sPS and iPP in blends' are:reduced. The reflection peaks of sPS in the blends are diffuse and not easily depicted in X-ray patterns. The crystallization rate of iPP is slightly affected by blending, while the crystallization rate of sPS is strongly reduced. |
