✦ Synopsis


Abstract

p‐Vinylbenzyphonic acid was prepared by means of the Arbuzov reaction between triethyl phosphite and p‐chloromethylstyrene followed by silylation with bromotrimethylsilane and methanolysis. The product, which is readily cross‐linked, is stabilized as dicyclohexycylammonium salt. Radical‐initiated polymerization occurs readily; homo‐ and copolymers found are slowly cross‐linked upon releasing dicyclohexylamine.
