  • Publication number: 20050090383
    Abstract: This invention relates to metal complex compositions, their preparation and their use as catalysts to produce polymers of conjugate dienes through polymerization of conjugated diene monomers. The used metal complex compositions are transition metal compounds in combination with an activator compound, optionally with a transition metal halide compound and optionally a catalyst modifier and optionally an inorganic or organic support material. The metal complexes comprises metals of group 3 to 10 of the Periodic System of the Elements in combination with activators, and optionally transition metal halide compounds of groups 3 to 10 of the Periodic Table of the Elements including lanthanide metals and actinide metals and optionally, catalyst modifiers, especially Lewis acids and optionally an inorganic or organic support material.

  • Patent number: 6242534
    Abstract: A rubber mixture containing at least one rubber component, at least one filler, and conventional additives that it contain at least one first gel as a filler, which is essentially comprised of a rubber, has a particle size of 3×10−9 to 1×10−6 m, and has a swelling index in toluene of 1 to 15, and at least the surface of this gel has acid or base groups, where these groups have not been produced by means of reaction with dithiophosphoric acid, and comprises: a) at least one second gel as an additional filler, which is essentially comprised of a rubber, has a particle size of 3×10−9 to 1×10−6 m, and has a swelling index in toluene of 1 to 15, which is in a position to undergo a neutralization reaction with the acid or base groups of the first gel and/or b) contains at least one substance as an additional additive, which is capable of undergoing a neutralization reaction with the acid or base groups of at least one gel.

  • Patent number: 6207757
    Abstract: A rubber composition which contains a rubber mixture that can be vulcanized with a vulcanizing agent, which includes at least one rubber component, at least one filler having nucleophilic groups, gel particles comprising a rubber, having a particle size between about 3×10−9 and about 1×10−6 m and a swelling index in toluene of about 1 to about 15 and whose surface has electrophilic centers, and a substance acting as a coupling agent between the filler having nucleophilic groups and the additional filler, the substance acting as a coupling agent having the following structure: X—R1—Si—(R2)3, wherein X is a nucleophilic group, R1 is an alkyl group having up to about 6 carbon atoms or a phenyl group, and R2 may be the same as or different from each other and from R1 and is an alkyl or alkoxy group having up to 6 carbon atoms and at least one of R2 is an alkoxy group.

  • Patent number: 6133364
    Abstract: A rubber composition, which contains a rubber mixture that can be vulcanized with a vulcanizing agent, which includes at least one rubber component, at least one filler, gel particles comprising a rubber, having a particle size between about 3.times.10.sup.-9 and about 1.times.10.sup.-6 m and a swelling index in toluene of about 1 to about 15 and whose surface has electrophilic centers, and a substance which acts as a coupling agent between the gel particles and which has the structure A--R--A, wherein A is a nucleophilic group, and R is a saturated or unsaturated hydrocarbon group. The rubber composition has improved hysteresis behavior in the vulcanized state so that when this rubber composition is used in tires, the rolling resistance is reduced and the wet slippage behavior is improved in relation to the conventional rubber compositions. A method of formulating the rubber composition as well as a composition useful for tire treads and vehicle tires containing the composition are disclosed.
