Abstract

Ziegler-Natta catalysts are deposited on a support consisting of inert spherical particles (I) which have uniform size of pref. 0.1-8mm. and are pref. composed of the polymer produced in the reaction. The catalyst is strongly bonded to the particles, preventing break-up during use. The uniformity of particle size and shape creates a high bulk through which reacting materials flow easily. The supporting particles are made by fusion of the material, pulverisation of the fused mass and cooling of the product below fusion temp. in an inert gas.
