1. A method for preparing a resin composition, comprising:

(a) compounding a silicone composition with at least one first resin to form a master batch, the silicone composition comprising at least one polyorganosiloxane and at least one silicone resin soluble in the polyorganosiloxane, wherein a weight ratio of the at least one polyorganosiloxane to the at least one silicone resin is from about 99:1 to about 50:50, the silicone composition being present in the masterbatch in an amount of less than 50 wt. %; and

(b) compounding the master batch with at least one second resin to form a resin composition,

wherein the first resin and the second resin are each independently selected from a group consisting of a polyester resin, a polycarbonate resin, and a combination thereof; the resin composition comprises less than about 0.05 wt % of a metal organic salt, based on the total amount of the resin composition; and the silicone composition is present in the resin composition in an amount of 0.1 parts to less than about 2 parts by weight based on 100 parts by weight of the resin composition.
