A method for preparing a resin composition, comprising compounding a silicone composition comprising a polyorganosiloxane and a silicone resin soluble in the polyorganosiloxane with a first resin to form a master batch; and compounding the master batch with a second resin. A molded article comprising the resin composition has greatly improved impact strength.
