Abstract
Homogeneous metallocene and CGC catalyzed copolymerizations of ethene (E) and various substituted styrenes are examined. It is found that those with p-tert-butylstyrene (TBS) occur with dramatically higher degrees of incorporation and overall productivity than those observed under the same conditions with styrene. It is argued that that the sigma-donating effect of the tert-butyl substituent is responsible for this performance, effecting a destabilization of an otherwise dormant benzylic species following 2,1-insertion of the styrene. It was found possible to produce what is essentially TBS-alt-E (44% TBS with no sequential TBS units) using a standard constrained geometry catalyst at impressively high productivity 1.1.5 x 10(6) g/(mol(Ti).bar(E).h)] and unusually low concentration of TBS (0.7 M).
