Cellulose fiber-plastic composition containing a lubricant

This invention is directed to an extruded product, extrudable compound, and an extrusion method using a polymer, a cellulosic fiber, and at least one lubricant selected from the group consisting of ethoxylated esters of hydantoins, ethoxylated esters of sorbitol or sorbitan, or N, N'-bisalkanoylethylenediamines containing from 8 to 14 carbons of the alkanoyl group and compositions manufactured through such processes which simulate conventional wood products. The N,N'-bisalkanoylethylenediamines are new compositions of matter containing from 8 to 14 carbons of the alkanoyl group having a particle size range from about 90 to 150 mum, preferably from about 120 to 140 mum.
