Preparation of a supported catalyst for the polymerization of

A novel Phillips catalyst for the copolymerization of ethylene with .alpha.-olefins, contains, as a catalytically active component, a finely divided, aluminum silicate-supported, phosphorus-containing chromium catalyst. This can be prepared by applying at least one organic phosphorus(III), (IV) and/or (V) compound and at least one chromium(III) compound which does not react with said phosphorus compounds under the reaction conditions used, in succcession in any order or simultaneously, to a finely divided aluminum silicate hydrogel or xerogel with formation of a catalyst intermediate and activating the catalyst intermediate at elevated temperatures in an oxidizing atmosphere, with the result that the chromium catalyst is formed. The novel Phillips catalyst gives ethylene/.alpha.-olefin copolymers in which the comonomers are more uniformly distributed over the copolymer chains than is the case with ethylene/.alpha.-olefin copolymers which have been prepared with the aid of conventional Phillips catalysts. Moldings which have been produced from the ethylene/.alpha.-olefin copolymers obtained in the novel procedure have a particularly high environmental stress cracking resistance and an excellent creep rupture strength.

Phillips catalyst and its use for the preparation of

Propylene copolymers grafted with .alpha.,.beta.-ethylenically unsaturated carboxylic acids or derivatives and containing up to 35% by weight of other C.sub.2 - to C.sub.10 -alk-1-enes are obtainable by reacting the monomer to be grafted with a propylene copolymer at from 1 to 500 bar, where, in the absence of a free-radical initiator, from 0.01 to 1.0% by weight, based on the propylene copolymer, of the monomer to be grafted are admixed with the molten propylene copolymer, and the grafting reaction is carried out at from 210.degree. to 350.degree. C. The propylene copolymers according to the invention can be converted into crosslinked or crosslinkable propylene copolymers by admixing organic crosslinking agents.
