| 摘 要： | 用同步法合成了聚酯型聚氨酯／双酚Ａ环氧树脂互穿网络聚合物ＩＰＮ，测定了产物的力学性能，探讨了ＩＰＮ中聚氨酯对环氧树脂增韧过程，结果表明，当ＩＰＮ中聚氨酯／环氧树脂＝１５／１００（质量比）时，增韧效果较为理想，产物的综合力学性能最佳，而且通过ＩＰＮ增韧法与半－ＩＰＮ增韧法对比，发现ＩＰＮ的综合合增韧效果优于半－ＩＰＮ。

| Abstract: | Simultaneously interpenetrating polymer networks are prepared from polyester -urethane (s) (PU) and epoxy resin of bisphenol A (EP). Mechanical properties of IPNs lave been measured. The results showed that When PU/EP=15/85 (W) in IPNs,the toughening effect is very good and the mechanical properties is the best. Moreover,it is found that the comprehensive effect in INPs is better than semi-IPNs by comparison of the mechanical properties. |
