| titleOfInvention | Process for polymerizing alpha-olefin |
| abstract | A process for polymerizing one or more .alpha.-olefins of up to 20 carbon atoms which comprises contacting the one or more .alpha.-olefins under polymerization conditions with a catalyst system comprising: (a) a titanium halide-containing, magnesium-containing pro-catalyst 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 titanium compound in the presence of a polycarboxylic acid ester electron donor with or without a halohydrocarbon, (b) an organo-aluminium cocatalyst component, and (c) an organosilane selectivity control agent represented by general formula (i), wherein R1 is alkyl group of 13 to 30 carbon atoms, alkaryl group of 16 to 36 carbon atoms or aralkyl group of 16 to 36 carbon atoms; R2 and R3 are, independently, methyl or alkyl group of 13 to 30 carbon atoms or hydrocarbyloxy group of 1 to 6 carbon atoms; and R4 is a hydrocarbyloxy group of 1 to 6 carbon atoms. The process affords high catalyst productivity and produces polymer products that have broad molecular weight distribution while retaining low oligomer content properties. |
