Summary:PURPOSE:The titled resin particles which give a short molding time, a low moisture content and excellent fusion bonding of moldings, made by fixing calcium acetate on the surface thereof. CONSTITUTION:Styrene resin particles, preferably containing about 50wt% or more styrene (derivatives), are impregnated with about 1-15wt% expanding agent (e.g. propane, dichlorodifluoromethane, or cyclopentane) (about 0.1-4wt% solvent such as benzene may be used together). The expandable styrene resin particles thus obtained and calcium acetate of a particle diameter of about 0.1mm. or less are mixed using a twin-cylinder mixer, Henschel mixer, etc. to fix about 0.001-5wt% calcium acetate on the surface of the expandable styrene resin particles.
