Poly(α‐methylstyrene) (PMS) macromonomer having one vinylbenzyl group per polymer chain was prepared by the couplings of living PMS with p ‐chloromethylstyrene (CMS). Subsequently, well‐defined poly[acrylic acid (AA)‐ g ‐α‐methylstyrene (MS)] and poly[4‐vinylpyridine (4VP)‐ g ‐MS] graft copolymers composed of polyelectrolyte trunks were prepared by radical copolymerization of PMS macromonomer with AA and 4VP monomers, respectively. Binary poly(AA‐ g ‐MS)/poly(4VP‐ g ‐MS) or poly[AA · triethyl amine (Et 3 N) salt‐ g ‐MS)/poly(4VP‐ g ‐MS) graft copolymer blend films were cast from a benzene/methanol mixture. The morphological results of binary graft copolymer blends are discussed with respect to three‐phase separated structures.
