Abstract
Abstract A composition, glyceryl trimontanate is of the class of esters of montanic acid and has the following structural formula: WHEREIN R is a linearly saturated hydrocarbon chain having 24 to 32 carbon atoms. Glyceryl trimontanate is formed by esterifying montanic acid with glycerol. 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.
