    Abstract: Impact resistant graft polymeric materials are made by polymerizing 97 to 70 parts by weight of styrene, or a mixture of styrene and acrylonitrile in a weight ratio of from 90:10 to 65:35, in the presence of 3 to 30 parts by weight of a copolymer of 30 to 90 parts by weight of butadiene and 10 to 70 parts by weight of a C3-C18 alcohol ester of an unsaturated carboxylic acid, the copolymer having a K value of between 50 and 150. Specified carboxylic esters are n-butyl and 2-ethylhexyl acrylates, di-n-butyl and diisobutyl fumarates, and di-n-propyl maleate. The styrene-containing monomeric material may contain minor amounts of other monomers, e.g. alpha-methyl styrene, vinyl toluene or chlorostyrene. In addition to the carboxylic esters of the defined type, the butadiene copolymers may contain minor proportions of other monomers, e.g. methyl methacrylate, cyclohexyl acrylate and vinyl carbazole. The butadiene copolymer may be supplemented by other rubbery polymers, e.g. copolymers of butadiene and styrene or acrylonitrile, polychloroprene, polybutadiene and polyacrylates. The polymerization is preferably carried out by dissolving the butadiene copolymer in the styrene-containing monomeric material with the aid, if desired, of an organic solvent, and heating the mixture in the presence of a catalyst, e.g. di-tert.-butyl peroxide, benzoyl peroxide or azodiisobutyronitrile. Also present during polymerization may be regulators and lubricants.

    Abstract: Macromolecular polyformaldehyde is stabilized by mixing with it 0,01 to 10% by weight of a 2, 5-dimercapto-1, 3, 4-thiadiazole or a 2, 5-dimercapto-1, 3, 4-thiadiazole derivative of formula: wherein R1, R2, R3 and R5 represent hydrogen or alkyl, alkenyl, alkinyl, aralkyl, aryl, alkaryl or cycloalkyl radicals which may be substituted by hydroxyl, sulphydryl, carbonyl, carboxyl, amino, substituted amino, sulphonic acid or sulphonic acid ester groups, X and Y represent sulphur, sulphoxy or sulphonic groups, and R4 represents an alkylene, alkenylene, alkinylene, arylene or cycloalkylene radical, and R4 may be absent when the thiadiazole radicals are joined by a disulphide bridge. In examples acetylated macromolecular polyformaldehyde and a polyoxymethylene dimethyl ether are mixed with 2-dodecylmercapto-5 mercapto-1,3,4-thiadiazole, 2,5-bis-(3,6-dihydroxyphenyl-1)-mercapto-1,3,4-thiadiazole, 2-diethylaminoethylmercapto-5-mercapto- 1,3,4-thiadiazole and 2, 21-bis-(5, 51 dibenzylmercapto-1,3,4-thiadiazolyl)-disulphide. A list of suitable thiadiazoles is given.

    IPC: C01G3/06

    Abstract: Basic copper chloride is produced by oxidising cuprous chloride in an aqueous solution containing at least 20% sodium chloride, by weight, with oxygen or air, the pH of the solution being maintained at 3.5 to 5, preferably at 4.0-4.5, and the temperature being 0 DEG C.-120 DEG C., preferably 60 DEG -75 DEG C. The pH range may be obtained by the addition of alkali or alkaline earth liquors, compounds which are alkaline on hydrolysis, and amines, for example by adding solutions of sodium or potassium hydroxide, calcium hydroxide, ammonia, alkylamines, alkali metal phosphates or carbonates, and sodium methylate or ethylate. A dispersing agent, for example alkaryl sulphonates, ethoxylated long chain alcohols or carboxylic acids, alkyl sulphonates, or sulphosuccinic acid esters, such as succinic acid dinonyl sulphonate, may be added.

    Abstract: The invention comprises compounds of the general formula:- in which R and R1 are C1-C4 alkyl groups, X is an oxygen or sulphur atom and Y is C1-C4 alkoxy, allyloxy, phenoxy, nitrophenoxy, mono-or dialkylamino with 1 to 4 carbon atoms in the alkyl groups, cycloalkylamino, anilino, pyrrolidino, piperidino, C1-C4 alkylmercapto, C1-C4 alkyl sulphonyl, phenylmercapto or phenyl sulphonyl group. They may be obtained by reacting a compound of the formula (RO) (R1O) P(X) Hal in which Hal is a halogen atom, e.g. chlorine, bromine, or iodine, and R, R1 and X are as defined above with a 1-substituted butene-(3)-ol-(2) of the formula HO.CH.(CH2Y).CH =CH2 in which Y is as defined above. The reation may be carried out in the presence of an inert organic diluent, e.g. an aromatic, aliphatic or cycloaliphatic hydrocarbon or an aliphatic chlorohydrocarbon and it is advantageous to effect the reaction in the presence of an agent which binds hydrogen halide, e.g. pyridine, aniline, methylaniline, triethylamine, tripropylamine or other amine whose boiling point is above the reaction temperature or an alkali metal carbonate or bicarbonate. The reaction is preferably effected at about 10 to 130 DEG C. e.g. at 15 to 75 DEG C. Examples are given for the production of compounds in which R and R1 are each ethyl, X is S and Y is -NHC3H7, N(C2H5)2, SC2H5, p.NH.C6H5. p.SO2C6H5, SO2C2H5, phenoxy, cyclooctylamino, pyrrolidine, p.S.C6H5, ethoxy, allyloxy, and p.nitrophenoxy respectively. Examples are also given for the production of (CH3O)2P(S)O.CH(CH2SC2H5) CH=CH2 and the corresponding O,O- diisopropyl and O,O-dibutyl compounds, (CH3O)2 P(O)O CH(CH2.O. C6H5)CH=CH2, (iso C3H7O)2 P(S)OCH (CH2S.C6H5) CH=CH2, and (C2H5O)2 P(O)O CH(CH2SC2H5)CH=CH2. The products have insecticidal properties.

    Abstract: The invention comprises acid dyestuffs of the formula (I) where A is hydrogen, halogen, alkyl, alkoxy, carboxylic acid or sulphonic acid, R is hydrogen, alkyl, hydroxyalkyl or alkoxyalkyl, and each of R1 and R2 is hydrogen, halogen or alkyl, and in which A+R+R1+R2 together do not contain more than six carbon atoms and the two -NH-groups are meta or para to each other. The dyestuffs are made by reacting a compound of the formula (II) where A and R are as above, obtainable from a 1 - amino - 4 - halogenanthraquinone - 2 - sulphonic acid and an appropriately substituted meta- or para-phenylene diamine, with a carboxylic acid halide or anhydride of the formula (III) where X is halogen or an acyloxy radical containing an acyl group shown in formula III so that A+R+R1+R2 contain together not more than six carbon atoms. The dyestuffs dye animal fibres such as wool blue shades. Specification 282,409 is referred to.
