Effect of Mixing Conditions and Chemical Cross-Linking Agents on the Physicomechanical and Electrical Properties of NR/NBR Blends

Polymer–polymer combinations have received much attention because many polymer blends perform well in attractive new applications for which the individual polymer components are not suited. In the present work, the optimum conditions for mixing a 50/50 blend of Natural rubber/Acrylonitrile butadiene rubber determined by the physicomechanical and dielectric properties was found to be 140°C and 7 min. The low molecular weight compound, divinyl benzene enhanced the physicomechanical properties, the morphological characteristics, and reduced the domain size of the blend, as well as improving the aging properties.
