Abstract
An antigel agent composed of four types of antioxidants that allows polyamides to be blended with acrylonitrile/butadiene polymers with minimum generation of gels and yields a blend which can be extruded or sheeted to give a uniformed shaped product, for example, sheets and molded articles and is essentially free of plugging the screens of extruder used to extrude hose tube or sheet.
Claims5
A process of making a uniformly dispersed blend of acrylonitrile/butadiene polymer with a polyamide without gel formation comprising mixing the acrylonitrile/butadiene polymer with polyamide in the presence of a special chemical package consisting essentially of a mixture of alkylhydroquinone, thioester synergist, organic phosphite and an alkyl phenolic antioxidant at a temperature sufficient to melt the polyamide.
