Resumoα-Hydroxy-ω-carboxy-poly(methyl methacrylate) was prepared by anionic polymerization with an initiator obtained by the reaction between 1-[4-(2-tert-butyldimethylsiloxy)-ethyl]phenyl-1-phenylethylene and n-butyllithium, followed by termination with carbon dioxide and hydrolysis of tert-butyldimethylsilyl ether. The resulting polymer was found to be pure and to have a fairly narrow molecular weight distribution.
