Abstract
A method of agglomerating and desolventizing starch-hydrolyzed polyacrylonitrile graft copolymer using atomized, liquid water.
Claims3
A process of agglomerating and desolventizing starch-hydrolyzed polyacrylonitrile graft copolymer wherein said acrylonitrile is hydrolyzed to carboxamide and alkali metal carboxylate groups, comprising wetting particles of starch-hydrolyzed polyacrylonitrile copolymer during mixing with atomized, liquid water until the moisture content of the particles reaches about 17% to 22% by weight based upon the weight of the total composition and subsequently drying the particles at a temperature between about 25.degree. C. to 100.degree. C. to a moisture content of about 3% to 12.5% by weight of the total composition.
