Abstract
Elastomeric isoprene rubber compositions contain an effective amount of a coupling agent (A) comprising an organosilicon compound with coupling agent functions for inorganic/elastomeric fillers and include (B) at least one natural or synthetic rubber elastomer, (C) an inorganic filler as reinforcement filler, (D) other conventional constituents or additives comprising vulcanization agents; the coupling agent (A) being a functionalized organosilicon compound, including the following two compounds (i) and (2i), (i) being at least one functionalized siloxane corresponding to the formula (I): [(G)SiO][(G)SiO][GSiO][SiO][(G)(G)(Z—CO—N═N—CO-A)SiO]and (2i) being a mixture of at least one functionalized siloxane (i) with (3i) at least one functionalized organosilane also corresponding to formula (I) where m=n=o=p=0 (zero), q=1, a=0, 1, 2 or 3 and the sum a+a'=3.
