对等规聚丙烯/滑石粉复合材料注射成型后的样品进行了X射线衍射和显微分析，发现滑石粉/滑石粉复合材料具有明显的择优取向。与单独在聚丙烯中的情况相反，聚丙烯-滑石粉复合材料中的择优取向在熔融和新的结晶过程中幸存下来。结晶速率测量证实了滑石粉对聚丙烯结晶的成核活性。
X-ray diffraction and microscopical investigation of test samples prepared by injection molding from composites of isotactic polypropylene with talc revealed a preferred orientation of the talc and polypropylene matrix. Contrary to the situation in polypropylene alone, the preferred orientation in polypropylene–talc composites survived melting and a new crystallization. Crystallization rate measurements confirmed the nucleation activity of talc for polypropylene crystallization.
