Title: RUBBER COMPOUND FOR TYRE PORTIONS
Abstract:
A rubber compound comprising at least one cross-linkable unsaturated chain polymer base, silica functionalized with amine groups, a silane bonding agent belonging to the class of polysulphide organosilanes and a vulcanization system. The silica functionalized with amine groups is obtained through reaction of the silica with alkanolamine compounds having the general formula HOR1NR2R3 where : R1 is a straight or branched aliphatic chain with a number of carbon atoms ranging from 4 to 12; and R2 and R3, which are equal to or different from one another, are H or (CH2)nCH3, where n is an integer ranging from 0 to 4.
