초록

본 연구에서는 p-hydroxybenzoic acid(HBA)와 acryloyl chloride(AC)의 반응에 의해 방향족 카르복실기를 가지는 아크릴 단량체 p-acryloyloxybenzoic acid(ABA)를 합성하였으며, 합성된 ABA 단량체와 benzoyl peroxide(BPO) 개시제를 이용하여 톨루엔 용매 하에서 에틸렌-프로필렌-디엔 고무(EPDM)에 그라프트 공중합 시켰다. 합성된 단량체 ABA와 그라프트 공중합체 EPDM-g-ABA의 구조는 FT-IR, $^1H$-NMR 및 $^{13}C$-NMR 분광기로 분석하였으며, 개시제 함량과 단량체의 농도가 증가할수록 그라프트율이 높아지는 것을 확인하였다. 그라프트율이 증가할수록 인장강도와 영구압축줄음율과 같은 기계적 특성은 향상되었다. 또한 유리전이온도($T_g$와 초기 열분해 온도는 약간씩 상승하였다.

In this study, p-acryloyloxybenzoic acid(ABA) was synthesized with p-hydroxybenzoic acid(HBA) and acryloyl chloride(AC). The synthesized ABA monomer was grafted onto ethylene-propylene-diene rubber(EPDM) in toluene using benzoyl peroxide(BPO) as an initiator. The structures of ABA and EPDM-g-ABA were characterized by FT-IR, $^1H$-NMR, and $^{13}C$-NMR spectrometer. The graft ratio of EPDM-g-ABA increased with increasing the concentration of the initiator and the monomer. Mechanical properties such as tensile strength and compression set of the EPDM-g-ABA were improved with increasing the graft ratio. The $T_g$ and initial decomposition temperature were also increased with increasing the graft ratio.
