Resinous particles, method for production thereof, and uses therefor
 A polymeric monomer (A) having as a main component thereof a (meth)acryl type monomer which is subjected to aqueous suspension polymerization in the presence of a compound (B) which is substantially insoluble in water and sparingly soluble in the polymeric monomer (A). The compound (B) has at least one, preferably two or more, structural units, selected from the group consisting of --SH, --S--S--, --COOH, --NO.sub.2, and --OH. The use of compound (B), in the suspension polymerization of the (meth)acryl type monomer, represses of the production of by-produced minute particles due to sympathetic emulsion polymerization. The suspension polymerization permits production of (meth)acryl type polymer particles having high heat stability and a small range of particle diameters.
