ABSTRACT:
There is provided a process for polymerizing olefins by adding the same incrementally to a catalyst system comprising an aluminum halide, and an organo germanium halide or alkoxide in an inert solvent while controlling the temperature of reaction in the range of -30.degree. C to +30.degree. C, drowning the polymerization mixture in water, separating the organic phase therefrom, removing the solvent therefrom, and recovering a solid polymer in good yield.
