Abstract: Isotactic index improvement is achieved for C 3 and higher alpha olefins in systems containing a catalyst component comprising titanium supported on a magnesium halide support. The titanium component is formed by copulverizing the magnesium halide with one or more electron donorsfollowed bytreatmentwith liquidtitanium halide. The improvement is achieved by using a dialkylaluminum alkyl phenoxide component with the trialkylaluminum co- catalyst normally used. In slurry polymerizations, the isotactic index of the polymer has been improved. It is possible to achieve a variable melt flow index for polypropylene while maintaining good isotactic index. Isotactic index is retained at high levels even though the temperature and/or time of polymerization is varied.

Abstract: @ Isotactic index improvement is achieved for C 3 and higher alpha olefins in systems containing a catalyst component comprising titanium supported on a magnesium halide support. The titanium component is formed by copulverizing the magnesium halide with one or more eletron donor followed by treatment with liquid titanium halide. The improvement is achieved by using a dialkylaluminum monohalide component with the trialkylaluminum cocatalyst normally used. In non- slurry polymerizatins improvements in both activity and isotactic index have been achieved. In slurry polymerizations, the isotactic index of the polymer has been improved. It is possible to achieve a variable melt flow index for polypropylene while maintaining good isotactic index. Isotactic index is retained at high levels even though the temperature and/or time of polymerization is varied.
