Dual donor catalyst system for the polymerization of olefins |
| abstract |
The present invention provides a catalyst system that exhibits unexpected control of desired properties in polyolefin products. The catalyst system includes a titanium-supported catalyst in combination with a mixture of tetraethoxysilane (TEOS) and dicyclopentyldimethoxy-silane (DCPMS). This catalyst system has been found to be effective in making polypropylene and polypropylene copolymers havlng relatively high melt flow rates and moderately broad molecular weight distribution. |
