  • A new terpolymer, styrene-butadiene-benzyl methacrylate copolymer (BzMA-SBR) was synthesized by emulsion polymerization. After polymerization, XSBR ionomer was prepared by deprotection of benzyl group of BzMA through hydrolysis with NaOH. Carboxyl group contents can be controlled by changing the initial feed contents of BzMA. Structure of BzMA-SBR and XSBR were characterized by FTIR, $^1H$ NMR and DSC.
