    Abstract: Propylene copolymers which contain up to 35% by weight of other C2- to C10-alk-1-enes and are grafted with alpha , beta -ethylenically unsaturated carboxylic acids or carboxylic acid derivatives can be obtained by reacting the monomer to be grafted with a propylene copolymer at a pressure of from 1 to 500 bar, where from 0.01 to 1.0% by weight, based on the propylene copolymer, of the monomer to be grafted is added to the molten propylene copolymer in the absence of an initiator which decomposes to form free radicals, and the grafting reaction is carried out at a temperature of from 210 to 350 DEG C. The propylene copolymers according to the invention can be converted into crosslinked or crosslinkable propylene copolymers by admixing with organic crosslinking agents.

    Abstract: Partially crosslinked olefin polymers obtainable by reacting a) an ethylene polymer having a density of from 0.90 to 0.98 g/cm or b) a polymer comprising from 25 to 95 % by weight of a propylene homopolymer and from 5 to 75 % by weight of a propylene copolymer containing copolymerised C2-C10-alk-1-enes, where the comonomer content is from 1 to 45 % by weight, based on the total polymer, in the absence of initiators which decompose to form free radicals, with from 0.001 to 5 % by weight, based on the olefin polymers, of bismaleimido compounds of the formula (I) in which R is C1-C20-alkyl, where the alkyl radical may be interrupted by one or more oxygen atoms, C5-C7-cycloalkyl, C6-C15-aryl, where the cycloalkyl or aryl radical may in each case itself be substituted by one or more C1-C10-alkyl and/or C1-C6-alkoxy and/or C1-C4-dialkylamino groups, and a radical of the formula (II> R -Z-R (II> where R and R are each, independently of one another, C1-C10-alkyl, C5-C7-cycloalkyl or C6-C10-aryl radicals which may each themselves be substituted by one or more C1-C10-alkyl and/or C1-C6-alkoxy and/or C1-C4-dialkylamino groups, and Z is a C1-C10-alkyl group, a C1-C4-dialkylamino group, an oxygen atom or a sulphone group.
