| 摘 要： | 本文以过氧化二碳酸酯BPPD和芳叔胺DHET、DHPT、DMT、DMA组成的引发体系进行MMA聚合的研究。测定了聚合速率Rp,发现添加DHET、DHPT能促进MMA的聚合,缩短诱导期,提高Rp,其效果要比DMT、DMA为好。测定了E3和聚合速率方程。由ESR谱和端基分析证实DHET、DHPT芳胺组分产生的自由基能引发单体聚合。

| Abstract: | The polymerization of methyl methacrylatc (MMA) initiated by bis-2-phenoxyethyl peroxydicarbonate (BPPD) and N, N-di-2-hydroxyethyl-p-toluidine (DHET), N, N-di-2-hydroxypropyl-p-toluidine(DHPT), N,N-dimethyl-p-toluidine(DMT), N,N-dimethyl aniline(DMA) binary systems has been studied. The polymerization rate RP and overall activation energy E3 of polymerization were determined respectively. It was found that the order of RP for initiation systems was BPPD-DHET≈BPPD-DHPT>BPPD-DMT, while the order of Eg was reversed. The rate equations for MMApolymerization in toluene solution were also determined. An initiation mechanism was proposed based on the results of ESRstudies and end group analysis. |
