Abstract
Partially crosslinked olefin polymers are obtainable by reacting a) an ethylene polymer having a density of from 0.90 to 0.98 g/cm.sup.3 or b) a polymer of from 25 to 95% by weight of a propylene homopolymer and from 5 to 75% by weight of a propylene copolymer with polymerized C.sub.2 -C.sub.10 -alk-1-enes, the comonomer content being from 1 to 45% by weight, based on the total polymer, in the absence of free radical initiators, with from 0.001 to 5% by weight, based on the olefin polymer, of a bismaleimido compound of the general formula (I) ##STR1## where R is C.sub.1 -C.sub.20 -alkyl which may be interrupted by one or more oxygen atoms, or is C.sub.5 -C.sub.7 -cycloalkyl or C.sub.6 -C.sub.15 -aryl, each of which in turn may be substituted by one or more C.sub.1 -C.sub.10 -alkyl and/or C.sub.1 -C.sub.6 -alkoxy and/or C.sub.1 -C.sub.4 -dialkylamino groups, or is a radical of the following formula (II)
