Abstract

Polymers containing not less than 80 per cent of acrylonitrile are dissolved in a solvent mixture of water, one or more water-miscible aliphatic liquids containing one alcoholic hydroxyl group and not more than 6 carbon atoms in the molecule, and at least one highly water-soluble salt selected from alkali metal thiocyanates, ammonium thiocyanate, guanidine thiocyanate, lithium bromide, lithium iodide, sodium iodide and zinc iodide, the salt or salts constituting at least 35 per cent of the solvent mixture, the solution also containing dissolved therein a protein, e.g. casein, gelatine and peanut protein, the weight of protein present being not greater than the weight of the acrylonitrile polymer. Polymers specified are polyacrylonitrile and copolymers of acrylonitrile with vinyl acetate, methyl acrylate, styrene, and vinyl and vinylidene chlorides. The watermiscible aliphatic liquids used are those of the parent Specification. The solutions may be formed into threads by extrusion into water or an aqueous bath containing at least 10 per cent of the solvent mixture used to form the solution, as described in Specification 729,472. Specifications 666,716, 670,268 and 670,269 also are referred to.
