Abstract: This invention relates to deodorizing odorous polyolefins. This is accomplished by mixing the odorous polyolefin with low concentration levels of an inorganic oxidant. Optionally, a fragrance is mixed with the odorous polyolefin mixture. Additionally, if desired, heat can be applied to the mixture.

Abstract: A catalyst system is made up of a catalyst and a cocatalyst. The catalyst component comprises a magnesium chloride support, a titanium trichloride, an aluminum trichloride and an organic phosphite. The cocatalyst comprises an organoaluminum compound. Exemplary of such a system is a MgCl.sub.2 supported TiCl.sub.3.1/3AlCl.sub.3 plus triphenyl phosphite as the catalyst and triethylaluminum plus diethylaluminum chloride and ethyl anisate as the cocatalyst. Such catalyst systems give both high productivity and low solubles in the polymerization of propylene. For ethylene polymerization, the cocatalyst can simply be triethylaluminum.

Abstract: A catalyst system is made up of a catalyst and a cocatalyst. The catalyst component is made by intensely mixing a titanium trihalide component with triaryl phosphite and aluminum trihalide adjuvants. The cocatalyst is an organoaluminum compound. An example of such a system is a ball milled mixture of TiCl.sub.3..sup.1/ 3AlCl.sub.3, triphenyl phosphite, and aluminum trichloride as the catalyst and diethylaluminum chloride as the cocatalyst. Such catalyst systems give both high productivity and low solubles in the polymerization of propylene. The catalytic activity and/or stereospecificity of the catalyst can be enhanced by heat treatment at a moderate temperature subsequent to milling the mixture.
