CARBON MICROPARTICLE AND PROCESS FOR PRODUCTION THEREOF

摘要

A process for producing carbon microparticles, characterised in that synthetic resin microparticles, metal-containing synthetic resin microparticles or child-particle-containing synthetic resin microparticles are subjected to carbonization baking, wherein the synthetic resin microparticles, the metal-containing synthetic resin microparticles or the child-particle-containing synthetic resin microparticles are produced by a process comprising mixing a polymer (A) such as polyacrylonitrile copolymer microparticles composed of a copolymer of an acrylonitrile monomer and a hydrophilic vinyl monomer with a polymer (B) that is different from the polymer (A) in an organic solvent to produce an emulsion and bringing the emulsion into contact with a poor solvent for the polymer (A), thereby causing the polymer (A) to precipitate; and the carbon microparticles.
