<p>Substituted, unsaturated, bicyclic imides and polymers thereof Imides of the formula I (I) in which E is allyl or methallyl and n is 1 or 2 and, if n is 1, R is hydrogen, alkyl having 1-12 C atoms, alkenyl having 3-6 C atoms, cycloalkyl having 5-8 C atoms, aryl having 6-10 C atoms or benzyl, or, if n is 2, R is -CmH2m-in which m is 2-20, arylene having 6-10 C atoms or a group of the formula II (II) in which T is methylene, isopropylidene, CO, O, S or SO2, are intermediates for the preparation of crosslinked polymers having excellent physical properties. The polymers can be used, in particular, for the preparation of glass fibre-reinforced and carbon fibre-reinforced plastics and heat-resistant composite materials, and as electrical insulation materials and whirl-sintered powder paints.</p> |
