Specified lactams are pyrrolidone, piperidone, e -caprolactam, capryllactam, oenanthiclactam, capriclactam, laurolactam, e -ethyl-e -caprolactam, #x-ethyl-#x-oenantholactam and methylenebis-caprolactam. Fillers, e.g. glass fibres, asbestos, graphite, gypsum, chalk, molybdenum sulphide, wood flour and fibres may be incorporated into the polymerization mixture. In Examples (1) to (6), e -caprolactam is polymerized in the presence of sodium caprolactam and: (1) benzimidazole-1-carboxylic anilide; (2) imidazole-1-carboxylic acid N : N1-diphenyl amide; (3) benzimidazole-1-carboxylic acid (N1-methyl) anilide; (4) 2-methylimidazoline-N(1)-carboxylic acid N : N1-diphenyl amide; (5) N : N - hexamethylene - bis - (carbamyldimethyl formamidine) and (6) (a) hexamethylene - bis - (N1 - carbamyl - 2 - methylimidazoli (b) hexamethylene-bis-(N-carbamyltriphenyl formamidine). In Example (7) pyrrolidone is polymerized in the presence of sodium methylate and imidazole-1-carboxylic diphenylamide.

    Abstract: Cycloaliphatic ketoxime hydrochlorides are prepared by the action of nitrosyl chloride or of nitrogen monoxide and chlorine on a cycloaliphatic hydrocarbon having 5 to 10 carbon atoms in the ring in the presence of hydrogen chloride while irradiating with active light where before the reaction commences or before the reaction subsides there is added such an amount of a mixture of by-products such as are obtained as a residue from the reaction mixture arising in a reaction of cycloalkanes with a nitrosation agent of the above mentioned kind after removal of the oxime hydrochloride and the excess reactants, so that the content of organically combined chlorine in the reaction solution is at least 0,5% by weight with reference to the amount of cycloalkane used. The addition of the by-products is said to prevent the formation of a yellow coating on the lamp or glass parts of the reactor which slows down the speed of reaction. The nitrosation residues used generally contain 20 to 40% by weight of organically combined chlorine and are preferably added so that the chlorine content is 0,5 to 5% based on the hydrocarbon. The reaction is otherwise carried out in known manner and the examples describe the preparation of the oxime hydrochlorides, of cyclo-hexanone and cyclo-octanone.

    Abstract: A dispersion for the stock sizing or surface sizing of paper comprises a polymer of (a) 4 to 40% of a quaternary vinylimidazolinium salt of formula where R2 is an alkyl, aralkyl or hydroxyalkyl group, R1 is aryl or R2 and Y is a radical of a strong acid which salt may be substituted in the 4- and 5-positions with low molecular weight alkyl groups and (b) at least 20% of an ester of formula where R3 is hydrogen or a C1-4 alkyl and R4 is a C2- 8 alkyl, (c) acrylonitrile and/or (d) one or more other ethylenically unsaturated polymerizable compounds. Preferred proportions are 7-20% of the salt, 40-80% of the ester and 20-50% of the acrylonitrile. Details of the preparation are given in Specification 976,547. Specification 897,804 also is referred to.ALSO:Paper is stock sized or surface sized with a dispersion of a copolymer of (a)4-40% of a quaternary vinylimidazolinium salt of formula:- where R2 is an alkyl, aralkyl or hydroxyalkyl group, R1 is R2 or aryl and Y is a radical of a strong acid, which salt may be substituted in the 4-or 5-position with low molecular weight alkyl groups and (b) at least 20% of an ester of formula:- where R3 is hydrogen or a C1-4 alkyl and R4 is a C2-3 alkyl (c) acrylonitrile and/or (d) one or more other ethylenically unsaturated polymerizable compounds. Preferred proportions are 7-20% of the salt 40-80% of the ester and 20-50% of the acrylonitrile. Specified paper are kraft, writing, printing and tissue papers and papers containing plastics fibres. The solids content of the dispersion may be from 2 to 20% for stock sizing and 0 5 to 5% for surface sizing. The dispersions may be added to the aqueous paper pulp, or at any point in the paper machine. It is particularly simple to apply the dispersion by means of a sizing press incorporated in the dry end of the paper machine. Also, finished paper if undersized, may be resized in a simple aftertreatment e.g. in a coating machine. In examples the dispersions are used to treat strips of unsized paper from 100% bleached sulphite pulp by dipping the paper in the dispersion and the dispersion is added to an aqueous suspension of bleached sulphite pulp and the mixture made into paper. Specifications 897,804 and 976,547 are referred to.
