摘要： The invention relates to an elastomer mixture resulting from the modification of a diene elastomer by a coupling agent that inserts an alkoxysilane bearing a tertiary or secondary amine function into the elastomer chain. The mixture mainly comprises a diene elastomer coupled by the alkoxysilane group bearing a tertiary or secondary amine function bonded to the diene elastomer via the silicon atom. The invention also relates to a reinforced rubber composition which can be used in particular to make tyres and which comprises a reinforcing filler as well as an elastomer matrix including at least said elastomer mixture, and to a method for preparing same. The composition has improved hysteretic and mechanical properties in the vulcanised state and improved processability in the green state.

摘要： The invention relates to a plasticizing system that can be used for plasticizing a diene rubber composition, characterized in that it is based on an MES or TDAE oil and on a terpene/vinyl aromatic copolymer resin, in particular, limonene and styrene copolymer. The rubber composition exhibits an improved resistance to wear and to cuts, said composition being based on at leas tone diene elastomer, a reinforcing filler, a cross-linking system and a plasticizing system comprising between 5 and 35 pce of an MES or TDAE oil and between 5 and 35 pce of a terpene/vinyl aromatic copolymer resin (pce = parts by weight per 100 parts of elastomers). The invention also relates to a method for preparing a composition of the aforementioned type, to the use of this composition for producing a finished article or semi-finished product for use in a tire or a tire/motor vehicle connecting system, particularly a tire tread.

摘要： The inventive plasticiser system for plasticising a diene rubber composition is based on MES or TDAE oils and an C5/vinylaromatic fraction resin, in particular a fraction C5 and styrene copolymer. Said rubber composition exhibits an improved abrasion and cut resistance and is based on at least one type of diene elastomer, a reinforcing filler, a reticulation system and a plasticiser system comprising from 5 to 35 pce of MES or TDAE oils and from 5 to 35 pce of said resin (pce= parts in percent by weight of elastomer). Method for producing the inventive composition, the use thereof for producing a final or semi-final product for a motor vehicle ground holding system, in particular for a tyre and the belt thread thereof are also disclosed.
