摘要：

The surface structure of the 3TiCl3 AlC13 catalyst modified by donor has been studied by using ofESCA, XRD, IR, NMR and chemical analysis. The induced migration effect of donor has been revealed. Athree-layer model describing the surface structure of the catalyst modified has been proposed. According tothis model, the donor does not act at the active site. but changes the surface structure so as to influencethe stereoregulating ability of the catalyst through its induced migration effect.
