Abstract
1,198,753. Production of polyacrylonitrile fibres. INSTYTUT WLOKIEN SZTUCKZNYCH I SYNTETYCZNYCH. 4 April, 1968, No. 16223/68. Heading C3P. Fibres of acrylonitrile polymers having increased hydrophilic properties are obtained by subjecting a solution of an acrylonitrile polymer in a concentrated aqueous inorganic salt solution to hydrolysis with an inorganic base, and spinning the resultant solution. The acrylonitrile polymer may be a homopolymer or a copolymer with up to 20% by weight of other monomer component(s) such as methyl acrylate, methyl methacrylate, vinyl acetate, vinyl pyridine, itaconic acid or sodium allylsulphonate. The salt used in the concentrated aqueous solution may be sodium, thiocyanate, zinc chloride or calcium chloride, and the inorganic base may be a hydroxide of Na, K, Ca or Ba. The polymer can, if desired, be cross linked by including in the solution divalent metal ions, e.g. Ca or Ba ions, during or after hydrolysis. In examples, an acrylonitrilemethyl acrylate-itaconic acid copolymer is used.
