PURPOSE:A liquid monomer, a polymerization initiator, and a solvent are allowed to adsorb on the surfaces of a solid substance, then the polymerization is carried out in a nondispersing agent to effect the uniform and firm covering of a solid substance in high efficiency. CONSTITUTION:A liquid monomer such as (meth)acrylic acid, acrylonitrile, or vinyl acetate, a polymerization initiator such as benzoyl peroxide, azobisisobutyronitrole and a solvent such as a hydrocarbon or alcohol areallowed to adsorb on the surfaces of a powdery, granular or fibrous solid substance such as silica gel, molecular sieves, activated carbon or alumina, then, the polymerization is effected on the surface in a non-dispersing agent, preferably for 1-5hr. USE:The products are used as a carrier for functional materials, forming materials or fillers.
