摘要： The invention concerns a method for preparing a dilithium initiator for use in anionic polymerisation, a method for preparing by anionic polymerisation a living diene elastomer provided with a carbon-lithium group at each of its chain ends, and a method for preparing a three-block copolymer from said living diene elastomer. The inventive method for preparing a dilithium initiator consists in reacting in an aliphatic or alicylic hydrocarbon solvent a first reagent consisting of a dialkenyl benzene and a second reagent consisting of secondary butyl lithium, so that the ratio of the number of moles of the first reagent over the number of moles of the second reagent is substantially equal to 0.5, and said method is characterised in that it consists in causing said reagents to react in the presence of a diamine, so that the resulting initiator essentially consists of a double adduct resulting from the addition of a secondary butyl lithium on each of the double bonds borne by said dialkenyl benzene.

摘要： The invention concerns a method for obtaining a grafted diene elastomer comprising functional groups along the chain, a rubber composition comprising said grafted elastomer and having in particular hysteretic properties when crosslinked, and a method for preparing said composition. The invention also concerns a tyre running tread comprising said composition and a tyre with reduced running resistance incorporating said running tread. The method for obtaining said grafted elastomer consists in performing a free radical grafting reaction carried out in solution or in mass using a mercaptan type reagent and designed to graft said groups on the chain of an initial elastomer. The invention is characterized in that it consists in treating said initial elastomer with an antioxidant comprising at least one aromatic amine function prior to the grafting reaction, so that the grafted elastomer has a macrostructure almost identical to that of the initial elastomer. The inventive rubber composition comprises a reinforcing inorganic filler, and said grafted elastomer has a proportion of molar units derived from conjugated dienes higher than 30 %.

摘要： The invention concerns a method for obtaining a 1,3-butadiene homopolymer which consists in reacting a catalytic system in the presence of 1,3-butadiene and one or more mono-olefin(s) of 4 carbon atoms. The invention is characterized in that said catalytic system is based on at least: one conjugate diene monomer, one salt of one or more rare earth metals of an organic phosphoric acid, said salt being suspended in at least a saturated, inert hydrocarbon solvent of the aliphatic or alicyclic type, an alkylating agent consisting of alkylaluminium of formula AlR3 or HalR2, wherein R is an alkyl group, and a halogen donor consisting of alkylaluminium halide.

摘要： The invention concerns a rubber-based product, comprising at least a buffer zone for trapping oxygen outside said product so as to protect from oxidation at least a sensitive zone of said product, said or each buffer zone containing a composition based on at least an elastomer comprising at least an iron (III) salt designed to activate oxidation in said composition. The invention is characterised in that said salt is an iron (III) salt of a carboxylic acid of formula CnH2nO2, wherein n ranges from 2 to 5. Said product is obtained by incorporating by mechanical process said salt in said elastomer or elastomers contained in said composition, for said buffer zone. The invention is advantageously used in a tyre outer casing and provides improved rolling resistance.
