前文我们报告了含有芳香叔胺基的丙烯酸酯、甲基丙烯酸-4-N,N-二甲氨基苄酯(DMABMA)在过氧化二月桂酰(LPO)引发下的聚合动力学。从所得的聚合速度方程式及低的聚合活化能,认为DMABMA与LPO形成氧化还原体系而使DMABMA聚合,在本文第Ⅳ报中报道了DMABMA不仅能引发甲基丙烯酸甲酯的聚合,还参与聚甲基丙烯酸甲酯的链中,因此称这种既能参与引发聚合反应,又参与聚合物链中的引发“引发剂单体(initiatomer)”。这种含有可聚合胺引发体系的优点是,用于丙烯酸酯类医用
We have previously reported the kinetics of polymerization of aromatic tertiary amine containing acrylates, DMABMA, initiated with dilauroyl peroxide (LPO). From the obtained polymerization rate equation and low polymerization activation energy, it is considered that DMABMA forms a redox system with LPO to polymerize DMABMA. It is reported in the fourth report that DMABMA can not only initiate the polymerization of methyl methacrylate but also participate in polymethylol Methyl methacrylate, it is said to be involved both in initiating the polymerization and in initiating “initiator” in the polymer chain. The advantage of containing a polymerizable amine initiator system is that it is used in acrylics
