Abstract

The invention relates to preparing extruded articles by flowing one or more heat plastified streams of extrudable resinous thermoplastic materials through an extrusion orifice. In the invention at least one release agent or formulation comprising at least one release agent is introduced to at least a portion of one or more streams of extrudable resinous thermoplastic materials before the extrusion orifice.
