哌啶类化合物和有机过氧化物体系引发甲基丙烯酸甲酯聚合的研究

Studies on Methyl Methacrylate Polymerization Initiated with Piperidine Derivatives and Organic Peroxide Systems

本文研究了四种哌啶类环状脂肪胺哌啶(P)、2,2,6,6-四甲基-4-哌啶醇(TMP)、N-乙基哌啶(NEP)、1,2,2,6,6-五甲基-4-哌啶醇(PMP)分别与有机过氧化物过氧化苯甲酰(BPO)、过氧化月桂酰(LPO)、叔丁基过氧化氢(TBH)、过氧化苯甲酸叔丁酯(TBPB)组成的引发体系对甲基丙烯酸甲酯(MMA)聚合的影响。测定了聚合反应的表观活化能和动力学方程。

The polymerization of methyl methacrylate initiated with piperidine derivatives (piperidine, 2,-2, 6, 6-tetramethyl-4-hydroxyl piperidinc, N-cthyl piperidine, 1,2, 2, 6, 6-pentamethyl-4-hydroxyl piperidine) and organic peroxides (benzoyl peroxide, lauroyl peroxide, t-butyl hydroperoxidc, t-butyl peroxybcnzoatc) systems was studi-ed in this paper. The polymerization rate cquation and the activation energy of polymerization were determined respectively.
