摘要： It now has been found that the properties of rubber compositions comprising rubbers having an unsaturated carbon chain can be improved by including therein, a minor property-improving amount of at least one hydroxy-benzimidazole oxide compound of the formula ##STR1## wherein R is hydrogen, or a halogen, hydroxyl, lower acyl, lower hydrocarbyl, lower hydrocarbyloxy, lower hydrocarbylthio, carboxyl, cyano, amino, amide or --C(O)-- lower hydrocarbyl group, and R' is hydrogen, or a lower hydrocarbyl, lower hydrocarbyl amide, carboxamide carboxy acid, carboxy ester, or aryl group. When vulcanizates are prepared from such rubber compositions containing one or more fillers, the vulcanizates exhibit reduced low strain hysteresis and a high electrical resistivity.In another aspect of the invention, a filled vulcanizate made by vulcanizing uncured compositions of the type described above and containing a filler, particularly carbon black, is improved in filler interaction, hysteresis, modulus, compression set and resiliency. Rubber articles and portions thereof such as tires, hoses, springs, belts, treads, sidewalls and the like can be made utilizing the improved filled vulcanizates of the invention.

摘要： It now has been found that uncured rubber composition comprising rubbers having an unsaturated carbon chain and at least one carbon black can be improved by including therein, a minor property-improving amount of at least one aromatic heterocyclic di-N-oxide compound of the partial formula ##STR1## wherein the depicted carbon atoms are part of an optionally substituted aromatic ring, and R.sup.1 and R.sup.2 are each independently hydrogen, hydrocarbyl, halohydrocarbyl, hydrocarbyloxy, hydrocarbyl sulfonyl, hydrocarbyl thio, hydrocarbylsulfoxidyl, halogen, amino,--CN--OH--CHO--CH(O hydrocarbyl)2--C(O)R.sup.3--C(O)OR.sup.3--C(N--OH)R.sup.3--C(O)NR.sup.3 R.sup.6--CH.dbd.N--NH--C(O)OR.sup.3--CH.sub.2 OC(O)CH.sub.3--R.sup.4 YR.sup.3--C(O)NHR.sup.4 OH--C(NH)NR.sup.7 R.sup.8,or--C(O)NHN(R.sup.3).sub.2wherein each R.sup.3 is independently hydrogen or a hydrocarbyl group, R.sup.4 is a divalent hydrocarbyl group, R.sup.6 is hydrogen, hydrocarbyl, --R.sup.4 OR.sup.3, or --R.sup.4 COOR.sup.3 ; R.sup.7 is hydrogen or a hydrocarbyl group; R.sup.8 is hydrogen or a hydrocarbyl, an amino, or a hydroxyl group; R.sup.7 and R.sup.8 may be hydrocarbyl groups joined together to form a ring including the nitrogen atom, and Y is O, divalent S, --NH--, --S(O)-- or --S(O).sub.2 or R.sup.1 and R.sup.2 may be joined together to form further ring systems which may be saturated or unsaturated, and further substituted or unsubstituted. When vulcanizates are prepared from such uncured rubber compositions, particularly when the carbon black used therein has an average surface area of at least about 20 m.sup.2 /g, the vulcanizates exhibit reduced low strain hysteresis and exhibit no significant undesirable odor.In another aspect of the invention, a filled vulcanizate made by vulcanizing uncured compositions of the type described above and containing a filler, particularly carbon black, is improved in filler interaction, hysteresis, modulus, compression set and resiliency. Rubber articles and portions thereof made from such vulcanizates such as tires, hoses, belts, springs, treads, sidewalls, and the like can be made utilizing the improved filled vulcanizates of the invention.

摘要： Zinc dithiocarbamates are obtained in especially readily filterable form and high purity when zinc salts are first added, in aqueous solution, to the secondary amines underlying the zinc carbamates, so that a zinc salt complex of the amines is formed, and carbon disulfide and then sodium hydroxide solution are then introduced, with stirring, into the aqueous suspension so obtained, the temperatures being maintained in the range from room temperature to the boiling temperature of carbon disulfide until the reaction has completely finished.
