THERMOSETTING POLYMERS AND PREPOLYMERS OBTAINED BY CONDENSING ALKYLATED PYRIDINE WITH AROMATIC HYDROXYLATED MONOALDEHYDES

摘要

The object of the invention are new thermoset polymers and prepolymers, a process for their preparation, and their uses. The new thermoset prepolymers consist, at least in part, of the polycondensation products of one or more pyridine derivatives containing at least two activated methyl groups with one or more aromatic monoaldehydes containing at least one hydroxyl group. These prepolymers are used to prepare composite materials, in particular laminates, that can be used at high temperatures.
