    Abstract: Partially crosslinked polyolefin mixtures containing a) a polymer comprising from 25 to 97 % by weight of a propylene polymer (I) containing from 0 to 15 % by weight of copolymerised C2-C10-alk-1-enes and from 3 to 75 % by weight of a further propylene polymer (II) containing from 15 to 80 % by weight of copolymerized C2-C10-alk-1-enes, b) a randomly distributed ethylene copolymer containing from 5 to 20 % by weight of copolymerised C3-C10-alk-1-enes and having a density at room temperature of from 0.89 to 0.925 g/cm , c) a rubber-like material having a Shore A hardness of from 30 to 90, and d) a bismaleimido compound 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.
