Diene elastomer based rubber composition, useful in e.g. road-holding system for motor vehicles, tires and tire running tread, comprises zinc, reinforcing filler and sulfur based reticulation system comprising a zinc carboxylate

摘要

Diene elastomer based rubber composition (I) comprises zinc (less than 2 parts by weight per 100 parts of elastomer), reinforcing filler and sulfur based reticulation system comprising a zinc carboxylate. Diene elastomer based rubber composition (I) comprises zinc (less than 2 parts by weight per 100 parts of elastomer), reinforcing filler and sulfur based reticulation system comprising a carboxylate zinc of formula ((RCOO) 2Zn). R : hydrocarbon (preferably with 1-11C), 1-16C alkyl, 1-16C aryl, 1-16C aralkyl or 1-16C alkaryl. Independent claims are included for: (1) the preparation of (I) comprising incorporating (by mixing) the reinforcing fillers and the sulfur based reticulation system to the diene elastomer; and (2) road-holding system for motor vehicles, tires, semi-finished product for manufacturing tires and tire running tread comprising (I).
