Abstract
An olefine polymerization catalyst comprises (1) a solid transition metal compound, (2) an organo-compound of a non-transition metal compound, (3) a tetra-alkyl diamine and (4) a phosphine oxide derivative, wherein one of the compounds (3) and (4) has been milled with the transition metal compound. The catalyst system may optionally include a polyene. The catalyst combines good polymerization activity with a low yield of soluble polymer.
