摘要： A powdery rubber is produced by mixing an anionic or nonionic rubber latex with an aqueous solution of an anionic water soluble macro-molecular compound which is dissociated in water to give negative charge; adjusting the pH to an acidic condition; adding to the aqueous solution either a cationic polymer which is water soluble in an acidic condition or a cationic surfactant which causes a coacervation with the anionic water soluble macromolecular compound in an acidic condition to separate the rubber particles from the rubber latex under coacervation and adding an emulsion of a synthetic resin having a glass transition temperature higher than 30.degree. C. to the rubber particles at a ratio of 1 to 50 wt.% (as a solid content) to the solid content of the rubber latex and dehydrating and drying the resulting powdery rubber.
