THE INVENTION RELATES TO A CHLOROFLUOROCARBON RESISTANT RESIN COMPOSITION CHARACTERIZED BY COMPRISING AN AGGLOMERATED GRAFT POLYMER (Y) OCCURRING IN CLUSTERS HAVING A WEIGHT AVERAGE PARTICLE DIAMETER OF 0.8-2.0 mM AS FORMED FROM A SMALL PARTICLE DIAMETER GRAFT POLYMER (Y) OBTAINED IN A GRAFTING DEGREE OF 10-40 WEIGHT BY POLYMERIZING 60-20 WEIGHT OF A MONOMER MIXTURE COMPRISING 30-45 WEIGHT OF A VINYL CYANIDE COMPOUND AND 70-55 WEIGHT OF AN AROMATIC VINYL COMPOUND IN THE PRESENCE OF 40-80 WEIGHT OF A RUBBER LIKE POLYMER HAVING A WEIGHT AVERAGE PARTICLE DIAMETER OF 0.05-0.2 mM AND A COPOLYMER (Z) OBTAINED BY POLYMERIZING 35-45 WEIGHT OF A VINYL CYANIDE COMPOUND WITH 65-55 WEIGHT OF AN AROMATIC VINYL COMPOUND AND HAVING AN INTRINSIC VISCOSITY OF 0.6-0.9, THE RUBBER LIKE POLYMER ACCOUNTING FOR 15-25 WEIGHT OF THE TOTAL COMPOSITION. THE RESIN COMPOSITION OF THE INVENTION IS SUPERIOR TO THE CONVENTIONAL RESIN COMPOSITION IN CHLOROFLUOROCARBON RESISTANCE.
