异丁烯酸甲酯／氰酸酯树脂半互穿聚合物的合成与表征

摘要

methyl ester （MMA） was added into melting cyanate ester resin （BACDy） with the presence of initiator. Bulk poly- merization occurred via monomer and prepolymer MMA reaction. Semi-interpenetrating polymer network-cyanate ester resin / PMMA （BACDy / MMA-SIPN） polymer material were prepared by synchronous and asynchronous synthesis. Meanwhile, several different components of SIPN system were discussed. The results show that, the formation of BACDy/MMA-SIPN network reaction conditions are greatly improved the mechanical properties and heat resistance. An optimal preparation conditions was proposed.%于加热熔融的氰酸酯树脂（BACDy）中加入异丁烯酸甲酯（MMA），在引发剂存在下，引发单体及预聚体MMA发生本体聚合，采用同步合成法和异步合成法分别制备互穿聚合物网络氰酸酯树脂／聚异丁烯酸甲酯（BACDy／MMA-SIPN）高分子材料，研究了几种不同配比的SIPN体系．结果表明，BACDy／MMA．SIPN网络形成的反应条件对体系的力学性能和耐热性能都有较大提高．给出了较合理的制备工艺条件．
