Abstract
The graft coplymerizations of maleic anhydride(MAH) and 2-vinylnaphthalene(2-VN) onto ethylene-propylene-diene terpolymer(EPDM) were carried out with benzoyl peroxide (BPO) as an initiator in several solvents at given temperatures. The synthesized graft copolymer, [(MAEV2)], was identified by IR spectroscopy. The effects of mole ratio of 2-VN to MAH, solvents, reaction time, reaction temperature, initiator concentration and EPDM concentration on graft copolymerization were examined. The maximum grafting efficiency was obtained at 1 : 1 mole ratio of 2-VN to MAH, 70℃ and in toluene. It was observed that grafting efficiency increased with increasing EPDM concentration. Decomposition temperatures of MAEV2 and ABS were 424℃ and 330℃, respectively. The thormal stability and light resistance of MAEV2 were better than those of ABS.

여러 가지 용매존재하에서 benzoyl peroxide(BPO)를 개시제로 사용하여 ethylene-propylene-diene terpolymer(EPDM)에 maleic anhydride(MAH)와 2-vinylnaphthalene(2-VN)을 주어진 온도에서 그라프트 공중합하였다. 합성한 MAH-EPDM-2-VN(MAEV2) 그라프트 공중합체는 IR 분광법으로 확인하였다. 그라프트 공중합시 MAH에 대한 2-VN의 몰비, 용매, 중합 시간, 중합 온도, 개시제 농도, 그리고 EPDM 농도등의 영향을 조사하였다. 그라프트 효율은 MAH에 대한 2-VN의 몰비값이 1.0일 때. 중합 온도는 70℃ 그리고 용매는 toluene일 때 가장 좋은 값을 나타내었다. EPDM 농도 변화에 따른 그라프트 효율은 EPDM의 함량이 증가할수록 증가하였다. MAEV2와 ABS의 열분해 온도는 각각 424℃와 373℃이었다. MAEV2의 내열성과 내광성은 ABS 보다 우수하였다.
