Abstract
Precrosslinked nitrile rubber polymers are prepared by interpolymerizing a polyol polyacrylate with butadiene and acrylonitrile to improve compression set, extrusion rate and die swell properties of the precrosslinked polymers and blends thereof with linear nitrile rubber polymers without sacrificing other physical and processing properties.
