The invention relates to a rubber composition that is free of zinc or that contains less than 0.5 phr of zinc, which can be used for the manufacture of tires, based on at least:

Rubber composition comprising a blocked mercaptosilane coupling agent

The invention relates to a blocked mercaptosilane of general formula I below:(HO)R&#x2014;Si&#x2014;Z&#x2014;S&#x2014;C(&#x2550;O)-Ain which:

Blocked mercaptosilane coupling agent

The invention relates to a rubber composition that is free of zinc or that contains less than 0.5 phr of zinc, which can be used for the manufacture of tyres, based on at least:

Rubber compound containing a blocked mercaptosilane coupling agent

Rubber composition, which can be used for the manufacture of tires, based on at least one diene elastomer, one reinforcing filler, one vulcanization system and, as antireversion agent, one itaconimidomaleimide compound of formula (R hydrocarbon radical):  Use of such a composition for the manufacture of a finished article or of a semi-finished product made of rubber intended for a motor vehicle ground-contact system, in particular of a tire.

Rubber composition comprising an itaconimidomaleimide

A rubber composition, usable for the manufacture of tires, is based on at least one diene elastomer, reinforcing filler, vulcanization system and, as anti-reversion agent, a citraconimidomaleimide compound of the formula (R=hydrocarbon radical): The composition may be used for the manufacture of a finished article or a semi-finished product made of rubber intended for a ground contact system of an automobile, in particular of a tire.

Rubber composition comprising a citraconimidomaleimide

The invention provides an elastomeric composition based on at least an isoprene elastomer, a reinforcing inorganic filler and, as (inorganic filler/isoprene elastomer) coupling agent, a citraconimido-alkoxysilane, in particular an N-[((C-C)alkyl-(C-C)alkoxysilyl)]-citraconimide. The isoprene elastomer is in particular natural rubber and the reinforcing inorganic filler a siliceous or aluminous filler of the highly dispersible type. Also provided is a process for preparing such a composition. The use of this composition for the manufacture of tires or semi-finished products for tires, in particular treads for heavy-vehicle tires, is also provided.

Rubber composition for a tire comprising a citraconimido-alkoxysilane as coupling agent

Siloxane polysulfide compound of the general formula (I) below: in which: The use of such a compound as diene elastomer cross-linking agent, in particular in a rubber composition for a tire.

Siloxane polysulfide usable as cross-linking agent, and process for obtaining such

A rubber composition based on at least a diene elastomer, a reinforcing filler and a siloxane polysulfide of the general formula (I) below: in which: The invention also concerns a process for preparing a rubber composition having an improved reversion resistance, a finished article intended for a suspension system of an automotive vehicle, in particular a tire.
