ABSTRACT:
Aliphatic monoolefins are polymerized employing a catalyst consisting of a first component formed by co-comminuting a mixture of a halogenated titanium compound, a magnesium or manganese dihalide, a Lewis base, and an aromatic compound which is normally liquid at about 25.degree. C; a second component consisting of a trialkylaluminum compound and a Lewis base; and, optionally, third component which is a dialkylaluminum halide.
