摘要: 采用熔融共棍的力一法制备r聚笨硫醚州屯氧树脂复合体系(PPS/EPS),用流变学力一法考察r双酚A型环氧树脂对复合体系内基体结钩的影响。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基体交联网络结钩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。

Abstract: Melt blending was employed to prepare poly(phenvlene sulfide)/epoxy resin composites(PPS/EPOs).The effect of epoxy on the structure of PPS/EPOs was investigated via rhcological 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 viscoclastic range extends due to presence of crosslinking network in the composites.
