Binary blends of acrylonitrile‐ co ‐butadiene rubber and ethylene propylene diene monomer rubber are immiscible. However, they can be made compatible by addition of a third elastomer viz., chlorinated polyethylene or chlorosulphonated polyethylene in small concentrations. Various sophisticated analytical techniques, e.g., ultrasonic velocity measurements in solutions, infrared spectroscopy of solution cast films, thermo‐mechanical analysis, processing characteristics through rubber process analyzer (RPA‐2000), determination of the vulcanizate properties, and also phase morphology studies by atomic force microscopy have been made to elucidate compatibility and its effect on end‐use properties of the evolved blends. © 1999 John Wiley & Sons, Inc.
