摘　　要：用原位多相聚合法合成了聚谜型聚脲基甲酸酯环氧树脂互穿网络聚合物 (IPN) ,得到了环氧树脂准分子复合材料 ,测定了产物的力学性能和热性能 ,探讨了聚醚分子量和聚脲基甲酸酯加入量对环氧树脂增强增韧过程的形响。结果表明分子量为 1 0 0 0的聚醚所合成的聚脲基甲酸酯的改性效果较好 ,加入量为1 2 .0 phr可使环氧树脂冲击强度提高 70 % ,拉伸强度提高 45 %。Polyurea (formic ester)/epoxy resin interpenetration polymer network and quasi-molecular composite have been synthesised by in situ multiphase polymerization.Mechanical and thermal properties have been measured,the influence of molecular weight of polyether and the effect of the content of polyurea (formic ester) have been studied.The results show that the addition of 12.0phr polyurea (formic ester) synthesiesed from polyether of 1000 molecular weight into epoxy resin have improved the impact strength 70% and tensile strength 45%,at the same time the thermal property doesn′t decrease.
