COMPOSITE PARTICLE OF SYNTHETIC ORGANIC COMPOUND POLYMER AND FERRITE AND PROCESS FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a process for preparing a composite particle of an organic compound polymer and ferrite which even enables manufacturing of the composite particle having a fine grain size through simplified steps, and the structurally stable composite particle manufactured through this process. SOLUTION: The composite particle wherein the ferrite is compounded with the synthetic organic compound polymer is formed by adding an aqueous solution of a metallic element ion which essentially comprises ferrous ion and an aqueous alkaline solution to an aqueous solution of the synthetic organic compound polymer obtained by polymerizing a monomer having multiple hydroxy groups and double bonds between carbons to generate a ferrite particle and to conjugate this with the synthetic organic compound polymer. A monomer having double bonds between carbons and an epoxy group or a polymer having a low degree of polymerization is seed polymerized with the composite particle formed through the process.
