Abstract: process for the production of water-soluble auxiliaries for the papermaking industry by reacting (a) 1 part by weight of a polyamidoamine obtained by condens ing 1 mole of a dicarboxylic acid having from 4 to 10 carbon atoms with from 0.8 to 1.4 moles of a polyalkylene polyamine having from 3 to 10 alkyleneamine units and containing up to 8 ethleneimine units per basic nitrogen atom with (b) 0.1 to 4 parts by weight of an .alpha..omega.-dichloro polalkylene oxide obtained by reacting a polyalkylene oxide having from 8 to 100 alkylene oxide units with a compound selected from the group consisting of a thionyl chloride and phosgene and then cleaving the reaction products by heating them to a temperature of from 70.degree. to 150.degree.c in the presence of a tertiary amine as catalyst, as crosslinking agent, at a temperature above 20.degree.c in aqueous solution or in a water-soluble organic solvent, the reaction being carried out to a point at which the viscosity of an aqueous solution containing 20% by weight of auxiliary is from 300 to 2,500mPas..

Abstract: A process for the preparation of water-soluble polymeric crosslinking agents by a two-stage reaction of di-secondary diamines with epichlorohydrin and/or dichlorohydrin, wherein, in the first stage, di-secondary diamines are condensed with epichlorohydrin and/or dichlorohydrin in a molar ratio of from 1:0.5 to 1:1 at a pH of from 9 to 12, and in the second stage the condensates obtained in the first stage are reacted with additional epichlorohydrin and/or dichlorohydrin at a pH of from 4 to 8.5. The watersoluble condensates thus obtained are crosslinking agents for polyamines, polyamidoamines, ethyleneimine-modified polyamidoamines and polyether-amines. The crosslinking reaction gives water-soluble condensates, which possess a high cation activity and may be used as retention aids, drainage aids and flocculants in the manufacture of paper.

Abstract: 1,2-Dicyanocyclobutane is made by the dimerization of acrylonitrile at 200-400 DEG C. under pressure after addition to the acrylonitrile of 0.1-30% by weight of an ester of a carboxylic acid or an ester of an inorganic acid. The specified carboxylic acid esters include esters of aliphatic and aromatic mono-and di-carboxylic acids. Trimethyl and triethyl borate are specified esters of inorganic acids. Examples describe the use of dibutyl phthalate and ethyl acetate. The reaction mixture may include a polymerization inhibitor, e.g. hydroquinone, ammonia or water.

Abstract: A self-extinguishing composition comprises a propylene polymer, antimony trioxide and an organic bromine compound containing 45 to 93% of aliphatically combined bromine and having a boiling point above 200 DEG C. The propylene polymer may be a homopolymer or a copolymer with ethylene, butene, vinyl-acetate or -propionate, styrene or an ester of acrylic or of methacrylic acid; and the bromine compound may be a tetrabromocyclooctane, hexabromocyclododecane, phenyl - hexabromodecane, 1,2 - dibromo - 4 - (a ,b - dibromoethyl)-cyclohexane, N,N1,N11 - tri - (a ,b - dibromopropionyl) - trimethylene triamine, methylene-bis-(1,2 - dibromo - 1 - methylpropionamide), or a bromobutene-diol such as 2,3-dibromobutene-2-diol-1,4. Optional ingredients are other flameretardant agents, stabilizers, lubricants, dyes, fillers, antistatic agents and polymers, such as octabromodiphenyl, halogenated diphenyl containing Br and Cl, tribromotrichlorodiphenyl ether, dilauryl, thiodipropionate, bisphenols, aromatic sulphides, organic phosphites, benzophenone derivatives, thiazole derivatives, epoxides, stearates, salicylates, carbon black, pentaerythritol, alkali salts of tartaric acid or ethylene diamine tetracetic acid, polyisobutylene, polyethylene, polystyrene, copolymers of ethylene with vinyl acetate or ethyl acrylate, chlorinated polyisobutylene, and chlorinated paraffins and/or polynuclear aromatic compounds. The bromine compounds may be added in the form of pastes or solutions in acetone or chloroform. The compositions find application as sheets, boards, tubes, fibres, hollow articles, mouldings and coatings.
