采用新型TiCl 4 /MgCl 2 /咪唑改性蒙脱土（IOHMMT）复合催化剂制备了聚丙烯（PP）/粘土纳米复合材料。通过这种方法，原位丙烯聚合实际上可以在硅酸盐层之间发生，并且不仅导致具有高全同立构规整度和分子量的PP，而且导致甚至在高粘土含量水平（高达19重量%）下的高度剥离的结构。
Highly exfoliated poly(propylene) (PP)/clay nanocomposites with obvious improvements in both the tensile strength and toughness have been prepared by a novel TiCl 4 /MgCl 2 / imidazolium-modified montmorillonite (IOHMMT) compound catalysts. Through this approach, in situ propylene polymerization can actually take place between the silicate layers and lead not only to PP with a high isotacticity and molecular weight, but also to a highly exfoliated structure even at high clay content levels (as high as 19 wt.-%).
