    Abstract: 1,162,225. Laminated synthetic resin films; seaming non-metallic sheet material. STANDARD OIL CO. 10 Aug., 1966 [11 Aug., 1965], No. 35799/66. Headings B5K and B5N. [Also in Divisions B2 and B8] A method of making a laminate comprises coating a surface of a biaxially orientated acrylonitrile polymer film consisting of an acrylonitrile homopolymer or of a copolymer of acrylonitrile with up to 5% by weight of at least one polyalkenyl monomer with an adhesive comprising (1) a mixture of a hydroxyl-terminated polyester and a polyisocyanate or (2) a blend of a copolymer of vinyl acetate and acrylic acid with a copolymer of ethylene and vinyl acetate, or (3) a polyurethane made by reacting 1: 6-hexamethylene diisocyanate and tolylene diisocyanate with trimethylol propane and a cellulose acetate-butyrate polymer having residual hydroxy groups, applying to the adhesive-coated surface of the acrylonitrile polymer film a film of a polyolefine which consists of a polymer of an alpha-olefine having the structure where R is hydrogen or C 1 to C 6 alkyl group; and bonding the two films together optionally with heat setting and/or curing of the adhesive during the bonding step. Many polyalkenyl monomers are disclosed. Specified polyolefines which may be melt-extruded into contact with the adhesive are the homo- and co-polymers of ethylene and propylene, polybutenes, polypentenes, polyheptenes and polyhexenes. The surfaces of the films may be pretreated, e.g. with a gaseous mixture of BF 3 and an oxidizing agent or an oxidizing agent or by the application thereto of flame or corona discharge prior to bonding. Articles, e.g. packages, may be made by the heat sealing of the polyolefine films and examples the folding and edge heat-sealing of laminates to form pouches. The laminates or the articles may be attached to foam layers or to woven or non-woven fabrics.

    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.
