Catalyst compositions that are highly tolerant of catalyst poisons comprising a catalytic derivative of a Group 4 metallocene metal complex and an Group 13 metal compound according to the formula R12M''(NR22), wherein R1 and R2 independently each occurrence is a hydrocarbyl, silyl, halocarbyl, halohydrocarbyl, hydrocarbyl-substituted silyl, halocarbyl-substituted silyl, or halohydrocarbyl-substituted silyl group, said R1 and R2 having from 1 to 30 carbon, silicon, or mixtures of carbon and silicon atoms, and M'' is a Group 13 metal, the molar ratio of complex to Group 13 compound being from 1:0.1 to 1:100. |
