| titleOfInvention | Process for polymerizing alpha-olefin |
| abstract | A process for polymerizing one or more .alpha.-olefins of up to 10 carbon atoms which comprises contacting the one or more .alpha.-olefin under polymerization conditions with a catalyst system comprising: (a) a titanium halide-containing magnesium, con-taining procatalyst component wherein the component is obtained by contacting a magnesium compound of the formula MgR'R", wherein R' and R" are, independently, alkoxide group, aryloxide group or halogen, with a halogenated tetravalent tita-nium compound in the presence of a halohydrocarbon and an alkyl ester of a polycarboxylic acid electron donor, (b) an orga-noaluminum cocatalyst component, and (c) an organosilane selectivity control agent represented by general formula (I) wherein R1, R2 and R3, are, independently, alkyl group of 1 to 12 carbon atoms; aryl group of 1 to 12 carbon atoms, alkaryl group of 1 to 12 carbon atoms, aralkyl of 1 to 12 carbon atoms or halogen; and R4 is hydrocarbyloxy of 1 to 2 carbon atoms. The pro-cess affords high catalyst productivity and produces polymer products that have broad molecular weight distribution while retaining low oligomer content properties. |
