摘要： The invention relates to a rubber composition made of at least a diene elastomer, reinforcing filler and an alkylcellulose in which the alkyl radical is a C1-C6 alkyl. The presence of F alkylcellulose, in particular ethylcellulose, improves the compromise between the raw-state properties of the rubber composition, such as processability, and the baked-state properties, such as the rigidity and the consistency of the rubber composition.

摘要： Radial tire having: a crown surmounted by a tread provided with at least one radially outer elastomer layer intended to come into contact with the road when the tire is rolling; two non-stretchable beads, two sidewalls connecting the beads to the tread, a carcass reinforcement passing into the two sidewalls and anchored in the beads; a crown reinforcement or belt positioned circumferentially between the carcass reinforcement and the tread; a radially inner elastomer layer, (tread "sublayer"), having a formulation different from the formulation of the radially outer elastomer layer, and positioned between the radially outer layer and the belt, wherein the sublayer comprises a rubber composition having at least from 30 to 100 phr of a nitrile/butadiene rubber having a content of butadiene units of between 40% and 90% by weight and more than 30 phr of a reinforcing filler. This sublayer limits the migration of plasticizers in the elastomer layer of the tread towards the inner elastomer compositions of the crown.

摘要： The invention relates to a rubber composition based on at least one diene elastomer, a crosslinking system and a reinforcing filler, characterized in that the composition also comprises a starch in a proportion of from 10 to 50 phr (parts by weight per hundred parts of elastomer) and an aqueous or water-soluble plasticizer in a proportion of from 3 to 30 phr, said aqueous or water-soluble plasticizer being water, or a mixture of water and glycerol in which the water is predominant by weight in the aqueous or water-soluble plasticizer. The invention also relates to a method for obtaining such a composition. The composition according to the invention can be used for preparing calendered or profiled products which are part of the manufacture of a tyre, such as, for example, a tyre tread.

摘要： The invention relates to a rubber composition containing at least one epoxide natural rubber (ENR), a reinforcing filler, and an alpha-methyl-styrene polymer resin as a plasticising agent. The invention also relates to the use of such a composition for producing a tread of a tyre with an improved property compromise regarding the grip on wet ground and rolling resistance.
