测定了在N-甲基-N-(2-羟乙基)-对-甲苯胺(HMT)存在下,MMA以过氧化物引发的聚合速率和聚合表观活化能.发现HMT对BPO、LPO引发的MMA聚合有促进作用,提高聚合速率.由聚合物端基分析证实了含有HMT的碎片,表明由芳叔胺HMT与BPO反应产生的自由基能引发单体聚合,BPO-HMT引发聚合为一氧化还原引发聚合.
The polymerization rate and the apparent activation energy of MMA were measured in the presence of N-methyl-N- (2-hydroxyethyl) -p-toluidine (HMT) Induced polymerization of MMA to improve the polymerization rate.Analysis of the polymer end groups confirmed the fragments containing HMT, indicating that the aromatic tertiary amine HMT and BPO generated by the reaction of free radicals can lead to monomer polymerization, BPO-HMT initiated polymerization of Redox initiates polymerization.
