Abstract
A process for preparing an acrylamide-based crosslinking monomer comprising reacting in the presence of a catalyst an isocyanate compound containing at least two isocyanate groups with one of acrylic acid or methacrylic acid. These acrylamide-based crosslinking monomers are used in the preparation of coating compositions, adhesive compositions curable by applying thermal or radiation energy, and in the preparation of cation or anion exchange membranes.
