ABSTRACT:
Heat resistant thermosetting prepolymers are prepared by reacting one or more methylated pyridines or pyrazines with one or more hydroxy aromatic aldehydes. The total number of methyl groups on the pyridine or pyrazine can vary from 2 to 4. The prepolymers are cured to produce heat resistant polymers and laminates with conventional fibers such as carbon fibers.
