    摘要: Crosslinked polymers which can be obtained by heating imides of the formula I ##STR1## in which E is allyl or methallyl, G is hydrogen or methyl, R is hydrogen, alkyl, alkenyl, cycloalkyl, aryl, benzyl, alkylene or arylene and n is 1 or 2, in the presence of a catalyst suitable for cationic polymerization. The use of the catalyst makes it possible to carry out curing at relatively low temperatures and within short reaction times. The polymers can be used, in particular, for the preparation of heat-resistant composite materials and they can also be used as electrical insulating materials and whirl-sintered powder paints.
