초록

본 연구에서는 저온유화중합을 통해 벤질메타아크릴레이트 (benzyl methacrylate, BzMA) 를 third monomer 로 사용하여 styrene-butadiene-benzyl methacrylate copolymer (BzMA-SBR) 를 합성하였다. 수산화나트륨 (NaOH) 을 이용하여 가수분해반응을 통해 BzMA 의 벤질 그룹을 deprotection 시켜 carboxylated styrene butadiene rubber (XSBR) 로 만든 후, Na-XSBR 아이오노머를 제조하였다. 중합 시 BzMA 의 투입량을 달리하여 XSBR의 카르복실기 (carboxyl group) 함량을 다양하게 조절하였다. FTIR (ATR), $^1H$ NMR, DSC 를 이용하여 합성된 BzMA-SBR, Na-XSBR 아이오노머의 구조와 특성을 분석하였다.

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.
