摘要
在加热熔融的氰酸酯树脂(BADCy)中加入甲基丙烯酸甲酯(MMA)单体(同步合成法)或MMA预聚体(异步合成法)并引发使其发生本体聚合,制备了具有半互穿聚合物网络结构的氰酸酯树脂/聚甲基丙烯酸甲酯(BADCy/MMA-SIPN),通过力学性能测试,红外及DSC分析研究了MMA含量对体系力学性能和热性能的影响。结果表明,互穿网絡的形成使氰酸酯树脂体系的力学性能和耐热性能都有较大的提高,冲击强度、弯曲强度及玻璃化温度分别提高了97.8%、58.6%和65℃。
The cyanate ester resin/PMMA（BADCy/MMA-SIPN） with semi-interpenetrating polymers network were prepared by adding methyl methacrylate（MMA） monomer（synchronous synthisis）or MMA prepolymer（asynchronous synthesis）into the melting cyanate ester resin（BADCy） and caused.The bulk polymerization occurred.The effects of MMA contents on the mechanical properties and thermal performance of the BADCy/MMA-SIPN were investigated by the mechanical testing,infrared and DSC analysis.The results showed that the mechanical properties and heat resistance of the cyanate ester resin system were greatly improved by the formation of interpenetrating network.The impact strength,flexural strength and glass transition temperature were increased by 97.8%,58.6%,and 65 ℃,respectively.
