Abstract

PURPOSE: To prepare resin particles useful as powder coatings, etc. and having excellent high-temperature fluidity, by suspension-polymerizing a specific monomer mixture in water containing a water-soluble inhibitor and inorganic powder, impregnating the product with an organic solvent, thermally expanding the impregnated product, and pulverizing the foamed product.
CONSTITUTION: A monomer mixture comprising (A) 30W85wt% of a hard monomer free of a crosslinkable functional group in the molecule and giving a homopolymer having a glass transition temperature of ≥90°C, (B) 10W60wt% of a soft monomer giving a homopolymer having a glass transition temperature of <90°C, (C) 5W40wt% of a crosslinkable functional group-containing monomer having a solubility of ≤15wt%, and (D) a chain transfer agent, is suspension-polymerized in water containing a water-soluble inhibitor and 0.5W30wt% of inorganic powder to give particles having an average particle size of 50μW5mm. The particles are impregnated with an organic solvent which penetrates in the particles but does not dissolves the particles, expanded at a ratio of 5W200 by heating under a reduced pressure of ≤300mmHg, and mechanically pulverized to give powder having an average particle size of 1W50μ.
