| titleOfInvention | Carbon black rubber coupling by mercaptopyridines |
| abstract | The invention relates to a sulfur vulcanization process comprising (a) a non-productive stage of mixing of a rubber composition comprising a polyisoprene rubber and carbon black, (b) a productive stage of mixing of a rubber composition further comprising sulfur and a vulcanization accelerator, and (c) vulcanization of said rubber composition and is characterized in that the non-productive stage of mixing is carried out in an internal mixer in the presence of 0.1 to 5 phr of a carbon black coupling coagent according to any one of formulae (I)-(IV) wherein R?1, R2, and R3¿ independently represent H or a C¿1?-C5 hydrocarbon group, optionally containing one or more oxygen, nitrogen or sulfur atoms, R?1 and R2¿, provided R1 is in the 4-position, or R?2 and R3¿ together with the carbon atoms to which they are attached may form a 5 or 6-membered ring, said ring optionally being substituted with a C¿1?-C5 hydrocarbon group, said group optionally containing one or more oxygen, nitrogen or sulfur atoms, n is 1 to 4, M is selected from Na, Zn, Mg, AL, Fe, and Te, and x is 1, 1.5 or 2. The invention also relates to rubber articles, such as pneumatic tyres, comprising the rubber vulcanizate obtained by said process. |
