Abstract
An improved method to prepare vinylpolystyrylpyridines comprises reacting a polymethylpyridine and an aromatic dialdehyde to form a 1:1 adduct and thereafter adding a methylvinylpyridine to terminate the adduct. Vinylpolystyrylpyridines are useful as cross-linking agents in bis-imide resin matrix compositions comprising reinforcing fillers.
