A resin that can be obtained by polycondensation, in basic medium, of:
- at least one phthalonitrile compound bearing, on the benzene ring thereof, at least one hydroxyl group and at least one other compound, which is a benzene compound bearing no —CN group(s) comprising, on the benzene ring thereof, at least one —OH group and optionally one or more substituents chosen from an amine group and an alkylene group bearing a hydroxyl group;
- or
- one phthalonitrile compound bearing, on the benzene ring thereof, at least one hydroxyl group and further comprising, on the benzene ring thereof, one or more substituents chosen from a phenyl group, a phenyl group bearing a —CHO group, an —O-phenyl group and an —O-phenyl group bearing a —CHO group.
