Potassium alcoholate was found to initiate the anionic polymerization of 2‐( N , N ‐diethylaminoethyl) methacrylate (AMA) to form poly[2‐( N , N ‐diethylaminoethyl) methacrylate] (PAMA). The molecular weight of the polymers was controlled by the monomer‐initiator ratio with a narrow molecular weight distribution. Increased reactivity of the initiator by chelation of the monomer to the cation may be important for the polymerization. Using potassium (4‐vinylbenzyl) alcoholate as an initiator, PAMA having a vinylbenzyl group was prepared which is a macromonomer having pH sensitive amino groups in each monomeric unit. By radical copolymerization with styrene, the PAMA macromonomer was incorporated as a graft chain.
