    Abstract: 1355265 Sulphur-containing silanes; rubber compositions DEUTSCHE GOLD-UND SILBER-SCHEIDEANSTALT 19 July 1971 [18 July 1970] 33710/71 Headings C3S C3E C3P and C3Q Novel sulphur-containing silanes of the formula A-X-Z, wherein A denotes -SCN, R 2 S-CSS- or (R 3 ) 2 N-CSS-, R denotes H, -SH or -N(R 1 ) 2 , R 1 denotes H, phenyl or C 1-5 alkyl, R 2 denotes a monovalent C 1-15 hydrocarbon or heterocyclic radical, R 3 denotes H or a monovalent C 1-15 hydrocarbon radical, or both R 3 substituents together with the nitrogen atom form a heterocyclic radical, X denotes a C 3-18 divalent hydrocarbon radical optionally interrupted by O, S and/or N atoms and optionally substituted by halogen, pseudohalogen, phenyl, halophenyl, (C 1-3 alkyl)phenyl or di(C 1-3 alkyl)- phenyl, Z denotes -SiR 4 (OR 5 ) 2 , -Si(OR 5 ) 3 , and R 4 and R 5 independently denote -CH 3 , -CH 2 CH 3 , -CH 2 CH 2 CH 3 , -CH(CH 3 ) 2 or -CH 2 CH 2 CH 2 CH 3 , and other silanes of the formula A-X-Z, wherein A alternatively denotes R 2 O-CSS-, are prepared by reacting halogen -X-Z with A-Me or with A-H in the presence of an acid binding agent, wherein halogen denotes Cl, Br or I and Me denotes ammonium, hydrocarbon-substituted ammonium, an alkali or alkaline earth metal, Mn, Fe, Co, Ni, Zn, Cd, Cu or Ag. Examples describe the preparation of 3-thiocyanatopropyl triethoxysilane, 3 - triethoxysilyl - propyl. ethyl - xanthogenate, 3 - thiocyanatopropyl tri - n - butoxysilane, and 2 - diethylamino- 4 - mercapto - 6 - (3 - triethoxy - silyl - propyl)- thiotriazine. The above compounds may be used either as vulcanization agents in the crosslinking of elastomers or as a binding agency between inorganic fillers and organic polymers, the required effects occurring in the presence of residual moisture in the mix and in the presence or absence of conventional accelerators or activators. Examples describe the vulcanization of styrene-butadiene and natural rubbers using the above compounds as vulcanizing agents added to the mix or used to pre-treat silica fillers, the vulcanization being carried out in the presence of sulphur and the presence or absence of conventional additives such as zinc oxide, stearic acid, dibenzothiazyl disulphide and diphenyl guanidine.

    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.
