PURPOSE: A resin prepared by applying a pentaerythritol phosphonate and a fluorine resin to a rubber modified styrene-based resin is provided which is excellent in mechanical properties, heat resistance and flame retardancy. CONSTITUTION: A resin comprises (A) 100 parts by weight of a rubber modified styrene-based resin, (B) 5 to 50 parts by weight of pentaerythritol phosphonate of formula 1 and (C) 0.05 to 2.0 parts by weight of a fluorine resin, wherein the rubber modified styrene-based resin comprises 20 to 100% by weight of a styrene-containing graft copolymer resin and 80 to 0% by weight of a styrene-containing copolymer resin. In formula, R1,R2 are each independently C1-10 alkyl, C5-7 cycloalkyl, C2-10 alkenyl, phenyl, C7-10 phenylalkyl or C8-10 phenylalkenyl. |
