| titleOfInvention | Manufacture of coated magnetic polymer grains |
| abstract | PURPOSE:To obtain the titled magnetic polymer grain of uniform susceptibility, globular shape and narrow grain diameter distribution having the grain surface which is uniformly coated by a composite polymer by a method wherein specific porous magnetic polymer grains are used as seed grains, a polymerizing monomer is added, and they are polymerized in the condition wherein the above materials are stirred up in an aqueous solution. CONSTITUTION:The aqueous solution, consisting of the mixture of iron salt or iron salt and other metallic salt, and the porous magnetic polymer grain, which is dispersed in the medium consisting of powderly or water and/or organic solvent, are mixed. The pH of said mixture is increased, a metal is precipitated in the porous polymer grains as a hydroxide and/or an oxide, they are heated up, if necessary, and the porous magnetic polymer grains containing a metal oxide are obtained. Using these polymer grains as seed grains, a polymerizable monomer is added, the polymerizable monomer is polymerized while it is being stirred up in an aqueous medium, and the magnetic polymer grains having the surface uniformly coated with a polymer can be obtained. |
