摘要：

Telechelic poly(methyl methacrylate) having a terminal OH and COOH group was prepared by anionic polymerization with the initiator made by the reaction between 4-[2-(tert-butyldimethylsiloxy)ethyl]-alpha-methylstyrene and n-butyllithium, followed by termination with carbon dioxide and hydrolysis of the tert-butyldimethylsiloxy group. The resulting polymer was characterized by osmometry, GPC, H-1 NMR, and potentiometric titration. It was confirmed that the polymer was pure and had a fairly narrow molecular weight distribution.
