Abstract
Ziegler-type catalysts of enhanced activity are produced by (1) suspending a finely divided polymeric support such as polyethylene in an alkanol solution of a magnesium compound such as magnesium chloride, (2) vaporizing the alkanol to deposit the magnesium compound on the support, (3) treating the magnesium compound impregnated support with a transition metal halide such as titanium tetrachloride in a hydrocarbon medium, and (4) reacting the product of (3) with an organometallic compound such as triethyl aluminum. The catalysts are particularly useful in polymerizing mono-1 olefins such as ethylene.
