摘要: 针对辐射固化复合材料树脂体系的原理,从引入具有辐敏性单体或基团入手,合成了活性稀释剂含硅丙烯酸酯和活性单体,如单官能、双官能的马来酰亚胺单体和芳香族酰亚胺单体,并对它们的结构进行了红外表征.实验结果表明,合成所得的树脂基体均可以实现辐射交联,且固化产物性能较优.Abstract: The use of electron beam (E-Beam) radiation to carry out rapid, pollution free, low energy crosslinking polymerizations of multifunctional vinyl monomers is an established technique. Polyimides and maleimides possess many useful properties such as high use temperature, excellent dimensional stability, low dielectric constants, and outstanding thermal and thermo-oxidative stability. Polyimides cured by electron beam radiation are conducted. In this work, to meet the requirement of electron beam curing polymerization, sensitive groups were introduced to monomers. Furthermore, the active diluents of siliceous acrylate, maleimide monomers and the aromatic imide monomers were synthesized. All of them were characterized by FTIR, so as the cured materials.
