Abstract: Novel silicon-containing derivatives of crystalline, high-trans-1,4 polybutadien e in which organosilicon-containing groups are bonded to the 1 ,2-vinyl carbon atoms along the main chain of the butadiene polymers through the carbon-silicon linkages. These derivatives of butadiene polymers are produced by the addition reaction of an organosilicon compound having one hydrogen atom directly bonded to the silicon a tom in the molecule to the double bonds in the 1,2-vinyl group butadiene polymers. Thes e derivatives having good compatability with siliceous fillers and when blended wi th filled diene rubbers are cured to elastomer compositions having excellent properties su itable for the production of tires.

Abstract: The present invention is directed toward anionic polymerization employing lithio amines mixed with an organic alkali metal compound and optionally, a chelating reagent. The lithio amines have the general formula (A)Li(SOL)y, where SOL is a solubilizing component, A is an alkyl, dialkyl, cycloalkyl or dicycloalkyl amine radical or a cyclic amine, and y is 0 or is from about 0.5 to about 3. The invention is also directed toward polymers and other products made using the initiator, and methods therefor. Further, the invention contemplates a polymer, a polymer composition and products therefrom, which include a functional group from the reaction product of an amine and an organolithium compound. The resulting polymers may be terminated with a terminating, coupling or linking agent, which may provide the polymer with a multifunctionality.

Abstract: The present invention is directed toward anionic polymerization employing lithio aldimines mixed with an organic alkali metal randomizer compound and optionally, a chelating reagent. The lithio aldimines have the general formula (A)Li, where A is derived from a substituted aldimine. The invention is also directed toward polymers and other products made using the initiator, and methods therefor. Further, the invention contemplates a polymer, a polymer composition and products therefrom, which include a functional group from the reaction product of a substituted aldimine and an organolithium compound. The resulting polymers may be modified with a terminating, coupling or linking agent, which may provide the polymer with a multifunctionality.

Abstract: PROBLEM TO BE SOLVED: To provide an intermediate transfer member simple in structure and capable of simplifying its manufacturing process while making good use of characteristic possessed by a rubber belt as the intermediate transfer member, and to provide its manufacturing method and an intermediate transfer device. SOLUTION: This intermediate transfer member is an endless belt type member disposed between an image forming body and a recording medium, driven to circulate by a driving member, temporarily transferring and holding a toner image formed on the surface of the image forming body on its own surface and transferring it to a recording medium. Elastic material is used as a base material layer 1, and a reinforcing member 2 is consecutively embedded in the rotating direction at a part out of an image forming area at both ends or one end of the layer 1.
