ABSTRACT OF THE DISCLOSURE Polyblends of nitrile rubbers and vinyl polymers, wherein the vinyl polymers have been prepared by polymerizing the vinyl monomer or monomers in the presence of a plasticizer therefor, and wherein said rubbers and polymers are blended together with or without an emulsion of additional plasticizer for the resultant polyblends, and the process of making said polyblends. The polyblends have a variety of uses such as in packaging, in cable jacketing, and so forth. They are particularly useful where flexibility is needed, such as in films, coatings, such as in coating fabrics, non-wovens, and like substrates. Further, when non-flammable properties are desired in the end product, it is a simple matter to choose a suitable plasticizer which will result in such properties. More importantly, the polyblends of the present invention are very readily and easily transformed to finely divided powder form by standard procedures which results, not only in ease of handling and shipping, but provides economic advantages in processing the same to the ultimate user or fabricator.
