A method for preparing a pitch for carbon fibers and a pitch for carbon fibers prepared by the same are disclosed. The method includes introducing a peroxide compound and ozone into a petroleum-process residual oil, followed by heat treatment for reaction. By the method, the pitch for carbon fibers, which exhibits excellent oxidative stabilization and oxidative incompatibility while having a high softening point and high strength, can be obtained at high yield at a relatively low temperature.

The present invention provides cellulose-based fibers including cellulose and at least one polymer selected from the group consisting of a polysiloxane, a polyacrylic acid, a polyacrylamide, an m-aramid, and a polyvinylalcohol/polystyrene copolymer, and a tire cord including the same. Furthermore, the cellulose-based fibers of the present invention have an advantage in superior elongation and tenacity of the prior cellulose fibers by blending at least one polymer having a functional group that is capable of a hydrogen bond with a hydroxyl group of a cellulose molecule.

Disclosed are a cellulose-based filament for a tire cord, a bundle including the same, a twisted yarn including the same, and a tire cord including the same. The cellulose-based filament is suitable for use in a tire cord has advantages in that strength deterioration due to twisting is remarkably low and elongation is improved, and thus the fatigue resistance is good.

The present invention relates to a novel polymer, an adhesive composition including the same, and a rubber reinforcing material treated with the same, and more particularly to an organic polysiloxane including a certain repeating unit, an adhesive composition including the same, and a rubber reinforcing material treated with the same. Because the organic polysiloxane and the adhesive composition including the same is superior in reactivity to a hydroxyl group, an amide group, or an amine group, and has high thermal resistance and low stiffness, the composition is preferably used for surface-treating a rubber reinforcing material such as a tire cord and make it possible to provide a rubber reinforcing material such as a tire cord having good properties.
