The chlorine atom in this compound undergoes a substitution reaction with the hydroxyl groups in quaternary phosphonium-modified chitosan to yield intermediate 2 and introduce an alkenyl group. Subsequently, using reverse emulsion polymerisation, acrylamide and intermediate 2 undergo a polymerisation reaction to yield quaternary phosphonium polyacrylamide.
