Polymerization of olefins employing a catalyst containing a titanium component derived from hydroxyalkyl aromatic compounds
A process is described for polymerizing at least one ..cap alpha..-olefin or a mixture of at least one ..cap alpha..-olefin and at least one polymerizable ethylenically unsaturated monomer in the presence of a supported Ziegler-Natta catalyst; the improvement which comprises employing as the transition metal component of such catalyst that which results from reacting (A) at least one titanium compound represented by the formula Ti(OR)/sub X/X/sub 4//sub -X/ wherein each R is independently a hydrocarbyl group having from 1 to about 20 carbon atoms; X is a halogen and x has a value from zero to 4; with (B) at least one compound containing at least one aliphatic hydroxyl group represented by the formula wherein each A is independently a divalent hydrocarbyl group having from 1 to about 10 carbon atoms; is independently hydrogen, a halogen atom, a hydrocarbyl group, a hydrocarbyloxy group or a halogen, nitro or hydrocarbyloxy substituted hydrocarbyl group or a halogen, nitro or hydrocarbyloxy substituted hydrocarbyloxy group, each such hydrocarbyl or hydrocarbyloxy groups having from 1 to about 20 carbon atoms; n' has a value of from 1 to 5, and each x independently has a value of from zero to 4; and wherein components (A) and (B) are employed in quantities which provide a molar ratio of (B):(A) of 0.1:1 to about 10:1.
