Redical Copolymerization of Acrylonitrile and Methylmethacrylate with Phase Transfer Tricaprylmetylammonium Chloride(II)-Monomer Reactivity Retio-
초록
회분식 고분자중합 반응기에서 NaS2O4 수용액상과 CCl4 유기상 접촉계면을 통한 액-액 불균일상계에서 tricaprylmethyl-ammonium chloride 상이동촉매를 사용하여 25℃, 질소기류하에서 acrylonitrile과 methylmethacrylate단량체의 공중합 반응을 행하여 초기 공중합 반응속도를 측정하였다. 측정된 초기 공중합속도를 사용하여 액-액 불균일계 접촉계면을 통한 공중합 반응에서 공중합 반응기구를 해석하였으며, 이로부터 단량체의 반응성비를 구하였다. 재래적으로 사용하는 Kelen-Tudos법 및 Fineman-Ross 법으로 구한 값과 비교하였으며, M1과M2 에 대한 반응성비는 각각 0.11과 2.30이었다.
The phase-transfer radical copolymerization of acrylonitrile with methylmethacrylate by tricaprylmethyl-ammonium chloride were investigated in Na2S2O4 aqueous-CCl4 organic two-phase system at 25℃ and under nitrogen atmosphere. The monomer reactivity ratios, r1 and r2 were obtained by the copolymerization mechanism with a cyclic phase-transfer initiation step and compared with those obtained by using the Kelen-Tudos method and Fineman-Ross method. Their values were 0.11 and 2.30, respectively.
