The object of the present invention is to provide a pretreating agent for electroless plating that is stable and soluble in organic solvents, a method of electroless plating with excellent adhesiveness using it and an electroless plated product. An object to be plated is pre-treated using a pretreating agent for electroless plating comprising a noble metal soap of naphthenic acid or a fatty acid having 5 to 25 carbon atoms or preferably using a pretreating agent for electroless plating additionally comprising an imidazole silane coupling agent or other silane coupling agent having metal capturing ability, and then electroless plated. The noble metal soap is preferably a palladium soap.

A process for producing an activated carbon fiber molding is disclosed which comprises spinning an isotropic pitch to thereby obtain pitch fibers, infusibilizing the pitch fibers to thereby obtain infusibilized fibers, heating the infusibilized fibers under a mechanical load to thereby obtain a molding and activating the molding. In this process, the infusibilized fibers and/or infusibilized fibers molding may be heated in an inert atmosphere so as to effect a light carbonization thereof and thereafter subjected to the subsequent step of the process. The pitch-based porous activated carbon fiber molding obtained by this process has a strikingly high bulk density and can sufficiently exhibit the specific properties of the activated carbon fiber, e.g. a large specific surface area, to thereby have a high adsorption efficiency.

Disclosed herein is a spinning nozzle having one or more discharge openings and one or more introduction openings located upstream the discharge openings for producing pitch-based carbon fibers characterized by the presence of one or more spiral members in each introduction openings. According to the nozzle of the present invention, part of the pitch which is introduced to the introduction opening flows down along the spiral member while the flow of the pitch is affected by the spiral member. The remaining pitch flows into the discharge opening without being in contact with the spiral member, and then both are spun after being mixed through the discharge opening to prepare carbon fibers having a random structure. Especially, the carbon fibers of higher performances can be prepared when a spiral having uneven outer diameters is employed.

摘要:
There is disclosed a process for producing pitch-based carbon fiber which comprises melt spinning an optically isotropic pitch or a mesophase pitch to form pitch fiber; subjecting the pitch fiber to liquid-phase oxidative polymerization in a solvent in the presence of an acid catalyst and a crosslinking agent to form infusibilized fiber; and carbonizing the infusiblized fiber. The above process enables low temperature and short time infusibilizing treatment of optically isotropic pitch fiber having a low softening point which has heretofore been difficult because of failure to preserve the original fibrous shape during infusibilization, and also efficient production of mesophase pitch-based carbon fibers as well as optically isotropic pitch-based carbon fibers each being improved in physical properties.

摘要:
A process for preparing pitch for matrix wherein an optically isotropic pitch is formed into a fibrous pitch, and the fibrous pitch thus obtained is nitrated with a nitration reagent in the presence of an acid catalyst. The resulting pitch can be carbonized with a low energy, is high in carbonization yield, low in softening point and excellent in moldability and impregnability.
