分析了3种不同工艺生产的牌号分别为1102K，T30S，F401的拉丝级聚丙烯（PP）的基本物理性能，采用升温淋洗分级、差示扫描量热仪、凝胶渗透色谱仪和偏光显微镜等研究了3种PP的立构规整性、相对分子质量及其分布、热稳定性能、晶体结构。与同类产品T30S，F401相比，1102K的等规指数和结晶度最高、球晶最小、相对分子质量分布最窄，有利于拉丝成型。

The basic physical properties of three drawing grade polypropylene including 1102K,T30S,F401 produced with different technologies were analyzed. The stereoregularity, relative molecular mass and its distribution, heat stability and crystal structure of the three kinds of polypropylene were studied by means of temperature rising elution fractionation (TREF), differential scanning calorimetry (DSC), gel permeation chromatograph (GPC) and polarized light microscopy (PLM). Compared with its counterparts T30S and F401, 1102K has the highest isotactic index, crystallinity and the smallest spherulite and the narrowest relative molecular mass distribution, being the most beneficial to drawing forming.
