【摘要】 <正> 文献曾简要报道叔丁基过氧化氢(TBH)与脂环仲胺哌啶(P)体系能引发甲基丙烯酸甲酯(MMA)聚合,而TBH与脂环仲胺吗啉(MP)也可作为厌氧胶的引发体系.为了研究吗啉类化合物对有机过氧化物引发聚合的影响,本文采用四种有机过氧化物:过氧化苯甲酰(BPO)、过氧化月桂酰(LPO)、TBH、过氧化苯甲酸叔丁酯(TBPB),研更多还原

【Abstract】 The effects of morpholine (MP), N-methyl morpholine (NMMP), and N-ethyl morpholine (NEMP) on methyl methacrylate polymerization initiated by benzoyl peroxide (BPO), lauroyl peroxide (LPO), t-butyl hydroperoxide (TBH), and t-butyl pero-xybenzoate (TBPB) respectively have been studied. It was found that in the polymerization using BPO initiator, the presence of MP decreased the polymerization rate RP, however, the NMMP NBMP promoted the polymerization, and the order of RP was BPO-NMMP > LPO-NMMP > TBH-NMMP > TBPB-NMMP. The activation energy of polymerization and the polymerization rate equation are determined.更多还原
