Anionic living polymerization of tertiary aminostyrenes (tAS) that serve as chemical links between two polymers are studied and the applications of the polymers to reversible recording materials are summarized in this paper. For preparing well‐defined polymers that have desired molecular weights and narrow molecular weight distributions by anionic living mechanism, three conditions are satisfied and the corresponding five experimental proofs are discussed using tAS as an example. The three poly(tertiary aminostyrene)s (PtAS) were prepared. The degree of quaternization of PtAS with n ‐butyl bromide could be controlled from 0 to 100%. The amino groups of PtAS were quaternized by p, p′‐bis(chloromethyl)azobenzene (CAB) to prepare the cross‐linked film and the network concentration was characterized by an equilibrium‐swelling test. Photochemical isomerization of CAB incorporated in PtAS was investigated in order to prepare the reversible recording materials. Copyright © 2003 John Wiley & Sons, Ltd.
