Abstract

In this study, the effects of nanolayered Silicate and acrylonitrile content on the viscoelastic behavior of NBR/PVC based nanocomposites were investigated. By increasing the nanoparticle and acrylonitrile content in the samples, the maximum elastic (\( {\text{S}}^{{\prime }} \)) and viscous (\( {\text{S}}^{{\prime \prime }} \)) vulcanization torques were increased. In the samples containing higher acrylonitrile groups, the peak of \( {\text{S}}^{{\prime \prime }} \) shifted to the shorter times, while by adding the nanoparticles to the compound, this peak shifted to the longer times. Drop in \( {\text{S}}^{{\prime \prime }} \) (\( {\text{DS}}^{{\prime \prime }} \)) declined by raising nanoparticle content. Samples with higher acrylonitrile content, showed the lower \( {\text{DS}}^{{\prime \prime }} \). Elastic torque at \( {\text{S}}_{\hbox{max} }^{{\prime \prime }} \) (\( {\text{S}}^{{\prime }} \) @ \( {\text{t}}_{{{\text{S}}^{{\prime \prime }} { \hbox{max} }}} \)), increased by increasing nanoparticle content. In the stress relaxation test, the ratio of the long time drops in modulus (DGl) to the short term drop in modulus (DGs) was corresponded with declining in the \( {\text{DS}}^{{\prime \prime }} \) of cure test.
