ABSTRACT:
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.
