A catalyst composition comprising a metallocene of a group 4 metal and an alumoxane is disclosed. The alumoxane is composed of both methylalumoxane and bulky alkoxyalumoxane monomers in the same polymeric alumoxane compound. Examples of the bulky alkoxy group of the alumoxane include di- and trisubstituted aliphatic carbon atoms, e.g., triphenylmethoxy, diphenylmethoxy, 1,3,3-trimethyl-2-norbornanyloxy. These mixed alumoxanes are made by either reacting MAO with the corresponding bulky alcohol, or by reacting the bulky alcohol with TMA followed by hydrolysis.

L'invention concerne une composition de catalyseur comprenant un alliage organométallique d'un métal du groupe 4 et un alumoxane. L'alumoxane comprend à la fois du méthylalumoxane et des monomères alcoxyalumoxane volumineux dans le même composé d'alumoxane polymère. On peut citer à tire d'exemples du groupe alcoxy volumineux de l'alumoxane des atomes de carbone aliphatiques à disubstitution et trisubstitution, par exemple, le triphénylmétoxy, le diphénylmétoxy, le 1,3,3-triméthyle-2-norbornanyloxy. Ces alumoxanes mélangés sont produits soit par réaction de MAO avec l'alcool volumineux correspondant, soit par réaction de l'alcool volumineux avec TMA suivie d'une hydrolyse.
