Abstract
1,2-Dicarboxyethyl-terminated polystyrenes were synthesized by anionic polymerization of styrene initiated by sec-BuLi, followed by reaction with dimethyl maleate, basic hydrolysis of the ester groups, acidification, and neutralization with NaOH. SEC indicated the absence of undesired coupling reaction as well as the absence of polymerization of dimethyl maleate. FTIR showed that the hydrolyse and the neutralization were complete. The functionality of the polymers was found to be very close to 2 by NMR spectroscopy and acid-bare titration
