A flame retardant resin composition is disclosed. An acrylonitrile- styrene based polymer, into which sulfonic acid groups and/or sulfonate groups have been introduced by sulfonating processing with a sulfonating agent containing less than 3 wt% of moisture, is contained in a resin to be made flame retardant, so that flame retardant properties will be conferred on the resin flame resistant. |
