Patent GB-717511-A (GB)
Title: Improved polymerised materials
Inventor: MILNE JOHN NOEL
IPC: C08L101/00
Filed: 1951-11-06
Abstract: Cross-linked polymerizable materials are produced by heating to at least 100 DEG C., with or without application of pressure, an interpolymer containing free carboxyl and nitrile groups attached to the same polymer chain, the ratio of carboxyl to nitrile groups being in the range of 1:10 to 10:1, the interpolymer being obtained by the interpolymerization of an alpha, beta ethylenically unsaturated carboxylic acid with an alpha, beta ethylenically unsaturated nitrile, with or without the addition of a third copolymerizable compound, the interpolymer containing at least 10 mols. per cent. of the unsaturated acid and unsaturated nitrile compounds in its structure.  Unsaturated acids and nitriles specified are acrylic, methacrylic, crotonic, angelic, tiglic, cinnamic, chloracrylic, maleic, fumaric, mesaconic, and citraconic acids and the corresponding nitriles.  Other polymerizable monomers specified are butadiene, vinyl formate, acetate, propionate, butyrate, stearate, benzoate, and crotonate, esters of allyl, methallyl, ethallyl, chlorallyl, crotonyl, and cinnamyl alcohols and but-1-ene-3-ol and pent-1-ene-3-ol with formic, acetic, lactic, butyric, glycollic, salicylic, oleic, benzoic, and phthalic acids, vinyl methyl, ethyl, isopropyl and butyl ketones, allyl substituted aldehydes and ketones, vinyl methyl, ethyl, isopropyl, butyl, phenyl, tolyl, naphthyl, vinyl, and propenyl ethers, allyl ethers, styrene, alpha methyl styrene, nuclear alkyl styrenes, ethyl acrylate, methyl methacrylate, ethyl chlormaleate, ethyl citraconate, vinyl chloride, N-vinyl urethanes, N-vinyl carbazole, N-vinyl pyrrole, N-vinyl piperidine, N-vinyl pyrollidone, and allyl substituted acetals and ketals. Polymerization may be carried out in bulk, in solution in a solvent such as acetone, or in aqueous emulsion containing a dispersing agent such as sodium lauryl sulphate, and may be effected with the aid of heat, ultra-violet light, and catalysts such as benzoyl peroxide, isopropylbenzene hydroperoxide, and, in aqueous emulsion, a mixture of potassium persulphate and sodium metabisulphite.  When polymerizing in aqueous emulsion the mixture of monomers and catalyst may be added gradually to the reaction mixture as polymerization proceeds.  The cross-linking of the interpolymers may be effected by conducting polymerization at temperatures above 100 DEG C., or by applying the heat treatment to the interpolymers after their preparation, preferably with the aid of an acidic catalyst such as phosphoric acid, ammonium chloride, ammonium phosphate, aluminium chloride, zinc chloride, p-toluene sulphonic acid, beta-camphoryl sulphonic acid, trichloracetic acid, and cetostearyl hydrogen phthalate.  The process may be applied to the cross-linking of mouldings and coatings, and also to fibres, as exemplified by the insolubilization of a pre-stretched fibre made from an acrylonitrile/acrylic acid/styrene terpolymer by heating at 130 DEG C.

Patent GB-1574110-A (GB)
Title: Process for the preparation of a vegetalbe protein extract
IPC: A23J1/14
Filed: 1978-05-31
Abstract: Vegetable proteins and phytic acid, or even antitrypsin factor in the case of soya bean, are separated at a pH slightly higher than the isoelectric pH of the said vegetable proteins, namely at a pH value within the range defined as ISO + 0.5 </= pH </= ISO + 1.2 with respect to the isoelectric pH designated by the abbreviation "ISO". This pH value is chosen because phytic acid and, where appropriate, the antitrypsin factor are relatively quite soluble at this value whereas most of the proteins are not and will not go into solution at this value. The separation is carried out during the manufacture of vegetable protein isolates or by washing flours, concentrates or isolates of vegetable proteins. Vegetable protein extracts low in phytic acid, or even in trypsin inhibitor in the case of soya bean, are obtained by this process.

Title: Production of cellular oxymethylene polymers
IPC: C08J9/30
Filed: 1965-06-23
Abstract: A closed-cell foamed oxymethylene polymer is made by forming a foam of an oxymethylene polymer in liquid form and a gas having no deleterious effects on the polymer at the temperature used and then solidifying the polymer. Preferably the oxymethylene polymer is a copolymer incorporating ethylene oxide or 1,3-dioxolane or end-capped with ether or ester groups.  Such a polymer may be foamed using conventional foaming agents, e.g. N,N1-dinitroso pentamethylene tetramine or azodicarbonamide, or may be heated with nitrogen to 200 DEG  C. under pressure in an autoclave equipped with paddle mixers. Alternatively unmodified oxymethylene homopolymer may be heated to 230 DEG  C. under 500 lb/square inch, whereby formaldehyde is released, and then releasing the pressure, or a copolymer may be heated with a small amount of homopolymer in the presence of a base, e.g. guanidine carbonate, and formaldehyde is generated and causes foaming. The polymer may be stabilised by antioxidants and anti-scission agents, e.g. 2,21-methylene - bis - (4 - methyl - 6t - butylphenol) and cyanoguanidine.
