ABSTRACT:
A fire-resistant polystyryl pyridine polymer is provided by two separate reactions: (1) the condensation of a methylated pyridine, an aromatic dialdehyde, and a methyl vinyl pyridine; and (2) by the addition curing of the condensation product. The condensation product provides a prepolymer suitable for forming a composite with another material such as graphite fibers, and the addition reaction provides a means to cure the prepolymer without eliminating volatile products.
