摘要： The present invention relates to a rubber composition based on a reinforcing filler and on an elastomer matrix comprising a highly saturated diene elastomer comprising at least five distinct units of A, B, C, D and E distributed randomly within the elastomer at respective molar fractions of m %, n %, o %, p % and q %, where m+n+o+p+q=100; m≥50; n+o+p+q≥10; and 15≥p+q≥2.This rubber composition enables a satisfactory degree of stiffness to be reached while maintaining hysteresis properties acceptable for use in the manufacture of tires for running vehicles.

摘要： The present invention relates to a novel catalytic system for polymerization, and more particularly for preparing conjugated diene polymers bearing a polar function at the chain end. This catalytic system is based on a metal salt of a rare-earth metal and, as alkylating agent, an organometallic compound based on a metal belonging to the 2nd column or the 13th column of the Periodic Table, capable of transferring a polar function to the diene elastomer during the conjugated diene polymerization step. The novel catalytic system makes it possible to reduce the steps for synthesizing a chain-end functionalized elastomer, while ensuring optimal functionalization, advantageously close or equal to 100%.

摘要： The invention relates to a diorganomagnesium compound of formula RB—Mg—RA, RB being different from RA, RB comprising a benzene nucleus substituted with a magnesium atom, one of the carbon atoms of the benzene nucleus ortho to the magnesium being substituted with a methyl, an ethyl, an isopropyl or forming a ring with the carbon atom which is its closest neighbour and which is meta to the magnesium, the other carbon atom of the benzene nucleus ortho to the magnesium being substituted with a methyl, an ethyl or an isopropyl, RA being an alkyl, a cycloalkyl or a benzyl, which may be substituted or unsubstituted, which diorganomagnesium compound is other than n-butylmesitylmagnesium. When used as co-catalyst of a metallocene, it makes it possible to increase the functional group content in the synthesis of a functional polymer.
