    Abstract: 1412610 Rubber stabilizers DEUTSCHE GOLD - UND SILBER - SCHEIDEANSTALT 27 Dec 1972 [27 Dec 1971] 59609/72 Headings C3P and C3Q [Also in Division C2] Stabilizers for vulcanizates of natural and synthetic rubbers (e.g. polybutadiene) are novel compounds of Formula I in which X and Y, which may be the same or different, each represents -SR 1 , -OR 2 , -CN, or -NR 3 R 4 and additionally X may be chlorine; R 1 is a C 1-12 alkyl or an aryl group; R 2 is a C 1-12 alkyl, C 5-8 cycloalkyl, aryl, allyl or methallyl group; R 3 and R 4 , which may be the same or different, each represents hydrogen, C 1-18 alkyl optionally substituted one or more times by -OH, -OR 5 (R 5 being C 1-18 alkyl) or by -CN, allyl, methallyl, C 5-8 cycloalkyl, aryl or a benzyl group; or one of R 3 and R 4 is α- or #- naphthyl or 4-phenylaminophenyl and the orther is hydrogen; or R 3 and R 4 together with the common nitrogen atom form a C 5-8 membered ring which is optionally substituted once or twice by C 1-4 alkyl groups and which, in addition to -CH 2 - groups and the nitrogen atom, optionally contains an oxygen or sulphur atom or the group -NR 6 - (R 6 being hydrogen or C 1-5 alkyl) ; and Z is C 1-8 alkyl, C 5-8 cycloalkyl, phenyl, benzyl or an acyl group of formula (R 7 being C 1-18 alkyl, benzyl or phenyl) or Z is a radical of Formula II wherein X and Y are as defined above.

    Abstract: 1385748 s-Triazine derivatives DEUTSCHE GOLDUND SILBER-SCHEIDEANSTALT 29 June 1972 [9 July 1971] 30423/72 Heading C2C [Also in Division C3] s-Triazine compounds of the general formula in which R 1 and R 2 , which may be the same or different, each represent a hydrogen atom, an aliphatic radical with 1 to 18 carbon atoms which may be substituted by one or more non-adjacent hydroxyl groups, an araliphatic radical with 7 or 8 carbon atoms, a cycloaliphatic radical with 5 to 7 carbon atoms which may optionally be substituted by 1 to 3 aliphatic side chains each containing 1 to 6 carbon atoms, a phenyl radical which may optionally be substituted with 1 to 3 aliphatic side chains each containing 1 to 6 carbon atoms, or R 1 and R 2 may form, together with the nitrogen atom, a heterocyclic ring system, with a total of 5 to 7 ring atoms which optionally contains one further hetero atom which is oxygen or nitrogen, X is the group -SCN or the group where R 1 and R 2 are as defined above, are used as vulcanization accelerators in the vulcanization of natural or synthetic rubbers of halogenfree dienes or mixtures thereof in the presence of sulphur and/or sulphur donors under the effect of heat and, optionally, pressure. The monothiocyanato-s-triazines can be prepared from the corresponding monomercaptotriazines by reaction with cyanogen chloride or cyanogen bromide in the presence of a hydrogen halide acceptor. The bis-thiocyanato-s-triazines can be prepared either by reaction of the corresponding chlorotriazines with potassium, sodium or ammonium thiocyanate in organic solvents, or by reacting the correspondingly substituted dimercaptotriazines with cyanogen chloride or cyanogen bromide in the presence of a hydrogen halide acceptor.

    Abstract: 1468853 Carbon black-filled thermoplastics DEUTSCHE GOLD-UND SILBER-SCHEIDEANSTALT 12 June 1974 [29 June 1973] 26031/74 Heading C3P Carbon black is incorporated in a thermoplastics material by a process which comprises adding the carbon black to the thermoplastics material in a continuous screw extruder at at least two points lying one behind the other in the delivery direction. Plastics material and part of the carbon black may be introduced together at a first inlet, and the distance between inlets may be 2 to 6, preferably 3 to 5 times the diameter of the kneader screw. The process may be used to produce concentrates which may be diluted with further plastics material. Examples describe the preparation of compositions of carbon black with (1 to 4) polyethylene, (2) polypropylene and (3) polystyrene.
