Abstract
Disclosed is a process for the making a polyvinylchloride/acrylonitrile-butadiene rubber blend by a) coating a polyvinylchloride resin with a stabilizer to form a precoated PVC; b) blending said precoated PVC with one or more acrylonitrile-butadiene rubbers to form a prestabilized NBR/PVC blend; and c) applying heat and pressure to intimately blend said prestabilized NBR/PVC blend into a fluxed NBR/PVC blend. Another aspect is a novel polyvinylchloride/acrylonitrile-butadiene rubber blend having a stabilizer homogeneously and uniformly distributed throughout the microscopic polyvinylchloride domains.
