摘　　要：采用熔融共混的方法制备了聚苯硫醚/环氧树脂复合体系(PPS/EPs),用流变学方法考察了双酚 A 型环氧树脂对复合体系内基体结构的影响。结果表明,环氧树脂的加入热氧化引发 PPS 基体化学交联,随环氧树脂用量的增加交联程度变大。PPS 基体交联网络结构的存在使得复合体系低频区动态模量显著增加,并呈现强烈的非末端效应,且复合体系对稳态剪切的敏感性下降。Melt blending was employed to prepare poly （phenylene sulfide ） /epoxy resin composites （PPS/EPOs）. The effect of epoxy on the structure of PPS/EPOs was investigated via rheological method. The results indicate that chemical crosslinking occurred on PPS matrix during blending process and the crosslinking degree increases with increasing of epoxy loadings. As a result, the dynamic modulus of the composites increases remarkably, presenting non-terminal effects at low frequencies. Moreover, the sensitivity to the steady shears decreases and the linear viscoelastic range extends due to presence of crosslinking network in the composites.
