ABSTRACT:
A powdered, free-flowing elastomer is prepared by mixing, in a preferred embodiment, a nitrile latex with sodium carboxymethylcellulose until the mixture thickens, adding the latex mixture to a coagulant solution with agitation, also adding polyvinyl chloride coating latex to the coagulant solution, filtering the liquid, drying the filter cake, and recovering the product having an average particle size of less than about 1 millimeter. During coagulation, the cellulose salt is converted to the insoluble aluminum CMC gel.
