A method of extruding a synthetic thermoplastic resin in which a processing aid in the form of a lubricant is added to the thermoplastic resin in order to facilitate processing of the thermoplastic resin. The improvement resides in using an organosilicon resinous composition as the lubricant for the thermoplastic resin.
