研究了水含量对环氧树脂/苯乙烯-烯丙醇共聚物（PScoPA）共混物断裂韧性的影响。水的进入具有双重后果：基体的相当大的增塑作用和基体与热塑性颗粒之间的界面的显著弱化。热塑性改性剂的加入减少了老化样品中断裂韧性的劣化。分析模型，基于周围的分散相颗粒的塑性空隙的增长，已被应用与合理的协议。
The influence of water content on the fracture toughness of epoxy/poly(styrene-co-allylalcohol) (PScoPA) blends with different amounts of modifier has been investigated. The water ingress has a double consequence: a considerable plasticization effect of the matrix and a significant weakening of the interphase between the matrix and the thermoplastic particles. The addition of thermoplastic modifier reduces, in the aged samples, the deterioration in fracture toughness. Analytical models, based on plastic voids growth around the dispersed phase particles, have been applied with reasonable agreement.
