Dynamically Cured Co-Polyester/Epoxidized Natural Rubber Blends: Influence of Epoxide Contents

Abstract:

Thermoplastic vulcanizates based on co-polyester and epoxidized natural rubber blends with various epoxide contents (i.e., 10, 20, 30, 40 and 50 mol% epoxide) were prepared. It was found that storage modulus and complex viscosity increased with increasing epoxide contents while tan δ decreased. Furthermore, increasing of glass transition temperature (T_g) of the rubber phase in the blend was observed with increasing epoxide content. Also, the tensile strength and elongation at break before and after aging increased with increasing epoxide content. Moreover, it was found that the epoxide content did not pragmatically effect on decomposition temperature (T_d) of the blends, but it caused decreasing in decompositionrate of the blends.
