摘 要: 综述了抗冲共聚聚丙烯的生产工艺及其组成、链结构及相形态的研究进展,重点介绍了分级的方法、链结构和相形态的表征手段。 The main production processes for impact polypropylene copolymer were reviewed. Several fractionation methods were emphasized,including single solvent fractionation, more solvent fractionation, temperature rising elution fractionation (TREF), cross fractionation (CF)and temperature gradient extraction fractionation (TGEF). Characterization means for composition and chain structure of IPCwere summarized, e.g. nuclear magnetic resonance (NMR), infrared spectrumetry-fourier transform (FT-IR) and differential scanning calorimetry (DSC). In phase morphology studying, application of technologies for scanning electron microscopy (SEM), transmission electric microscope (TEM), atomic force microscope (AFM), dynamic mechanical analysis (DMA) were introduced.
