Catalyst compositions that are highly tolerant of catalyst poisons comprising a catalytic derivative of a Group 4 metal complex and a Group 13 metal compound according to the formula R1 2Me(NR2 2), 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 Me is a Group 13 metal, the molar ratio of complex to Group 13 compound being from 1:0.1 to 1:100.
Cette invention concerne des compositions catalytiques qui offrent une tolérance aux poisons catalytiques et comportent un dérivé catalytique d'un complexe métallique du groupe 4 et un composé métallique du groupe 13 représenté par la formule générale R<1>2Me(NR<2>2), dans laquelle R<1> et R<2> sont indépendamment un groupe hydrocarbyle, silyle, halocarbyle, halohydrocarbyle, silyle à substitution hydrocarbyle, silyle à substitution halocarbyle ou silyle à substitution halohydrocarbyle, R<1> et R<2> comportant de 1 à 30 atomes de carbone, de silicium, ou des mélanges d'atomes de carbone et de silicium, Me est un métal du groupe 13, et le rapport molaire du complexe au composé du groupe 13 est compris entre 1 pour 0,1 et 1 pour 100.
