Effect of molecular weight on the properties of liquid epoxidised natural rubber acrylate (Lenra )/silica hybrid composites

This paper reports on the effect of molecular weight on the morphological and mechanical properties of liquid epoxidised natural rubber acrylate (LENRA)/silica hybrid composites prepared by sol-gel technique. The sol-gel reaction was conducted at different concentration of tetraethylorthosilicate (T...
