Abstract
A novel supported catalyst for polymerization of ethylene or its mixtures with C.sub.3 to C.sub.8 terminal olefins composed of (a) the solid reaction product of a titanium (IV) or vanadium (V) alkoxide, a hydrated magnesium stannate and an alkylaluminum dichloride, and (b) an organo-aluminum compound promoter. The catalyst produces polyolefin in good yield without any substantial production of polymer fines and the catalyst is quite sensitive to hydrogen induced chain termination processes leading to improved molecular weight control and rheology of the polymer product.
