    Abstract: Solutions of a polymer of at least one a ,b -olefinically unsaturated nitrile monomer and a polyalkenyl monomer in a polar solvent are useful in making films. Preferably the nitrile monomer is acrylonitrile, methacrylonitrile, a -chloroacrylonitrile, crotononitrile or vinylidene cyanide. The polyakenyl monomer preferably contains at least two CH2=C= groups separated by at least one other group, e.g. allyl or methallyl esters of unsaturated carboxylic acids, polyacrylates, -methacrylates or -maleates, divinyl or di(meth)allyl ether, diallyl or triallyl compounds, dienes (non-conjugated), divinyl or trivinyl compounds, diisopropenylbenzene, tetra-allyl or -vinyl compounds, diallyl vinyl silane, tri(meth)acryloyl-perhydrotriazine, bisacrylamides, (meth)allyl-substituted methacrylamide and poly-allyl or -vinyl ethers of polyhydroxy compounds; these monomers are preferably used in proportions of 0.05-5 parts by weight per 100 parts of nitrile monomer. If desired, up to 5 to 15% by weight of the nitrile monomer can be replaced by one or more mono-alkenyl monomers copolymerizable therewith. Preferred solvents include a dimethyl formamide - ethylene carbonate mixture, and nitro-ethane. Also listed are other amides, thio-amides, cyano-amides, methyl pyrrolidone, butyrolactone, tetramethyloxamide, lactams, tetracyanopentane, dimethylcyanamide, N-formyl compounds, sulphones, nitromethane, ethylene cyanohydrin, nitriles, dimethylaminophosphine oxide and tetramethyl-methane-phosphonamide. Instead of the organic solvents, inorganic salt solution systems may be used. Aqueous solutions of (substituted) guanidine thiocyanate are also suitable as solvents. The film-forming polymers may be prepared by batch, bulk, solution or suspension polymerization techniques but preferably are made in an aqueous medium in the presence of a redox catalyst composed of a water-soluble peroxygen compound, e.g. a persulphate, and an oxidizable sulphur compound, e.g. sodium meta-bisulphite, as promoter. A mercaptan may also be present. Preferably the co-polymers are made in two steps, the first step comprising the co-polymerization of a portion of the a ,b -olefinically unsaturated nitrile and all of the polyalkenyl monomer to high conversion, the second step comprising polymerizing (e.g. to 70-100% conversion) the remainder of the nitrile monomer, which may be added all at once or in increments, on to or in the presence of the polymer "seed" thus formed in the first step. Emulsifiers, surface-active agents or dispersing agents may be used throughout both the seed step and the main polymerization step. Examples illustrate solutions, and preparation, of copolymers of acrylonitrile with butanediol divinyl ether, tetramethylene diacrylate or divinyl benzene, and a copolymer of methacrylonitrile with tetramethylene diacrylate.
