ABSTRACT:
Styryl pyridine and styryl pyrazine cyanates are prepared by cyanating the reaction product of (A) a substituted pyridine and/or pyrazine with (B) a substituted aromatic aldehyde with the proviso that at least one of the components (A) or (B) contains a hydroxyl group which is susceptible to being cyanated. These cyanates can be homopolymerized or copolymerized with other materials to produce polymers having excellent high temperature resistance, good mechanical strength and excellent processability.
