Abstract Glyceryl trimontanate has excellent lubricating properties which are displayed upon its addition as an auxiliary agent to the reactive mixture for a synthetic plastic material; the resultant synthetic material is more easily formed such as by extrusion, and has improved shock resistance and transparency.
