    摘要： Vulcanizable, mercaptan- and/or xanthogen-disulfide-regulated polychloroprene rubber are produced by emulsion polymerization of chloroprene and, based on polymerizable monomer used, 0 to 30 parts by weight ethylenically unsaturated, other monomers copolymerizable with chloroprene in an alkaline medium by a process in which(1) 0.1 to 10 parts by weight of a tricyclic diterpene carboxylic acid containing at least two conjugated C.dbd.C double bonds per molecule, based on the polymerizable monomer used, and optionally(2) 0.1 to 5 parts by weight, based on polymerizable monomer used, fatty acid estersare used for their production.The polychloroprene produced in accordance with the invention may be used for the production of vulcanized rubber articles. The polychloroprene rubbers produced by the process according to the invention have a minimal tendency to foul metal molds. The pollution of wastewaters by the process according to the invention is minimal. The well-known favorable properties of polychloroprene remain unaffected.

    摘要： Toluene-soluble, sulphur-modified polychloroprene is obtained by emulsion copolymerization of chloroprene, sulphur and optionally further monomers which are copolymerizable with chloroprene and sulphur using a peroxy activator and subsequent working-up by stabilizing, stopping, degassing and isolating without separate peptization, in that polymerization is carried out in the presence of dithiocarbamates and/or xanthogenates and the activator is metered in continuously or batch-wise during the course of polymerization.

    摘要： 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. The rubber composition has improved hysteresis behavior in the vulcanized state so that with the use of this rubber composition in tires, the rolling resistance is reduced and the wet slippage behavior is improved in relation to conventional rubber compositions. A method of adding and blending the rubber composition as well as a composition useful for tire treads and vehicle tires containing the composition are disclosed.
