| 摘要 |
<p>The invention is directed to an extrudable compound, an extrusion method, and an extruded product comprising a polymer, a cellulosic fiber, and at least one lubricant selected from the group consisting of esters of ethoxylated hydantoins, esters of ethoxylated sorbitol or sorbitan, or N,N'-bisalkanoylethylenediamines containing from 8 to 14 carbon atoms in each alkanoyl group. Extruded products manufactured according to the invention simulate conventional wood products. The invention is further directed to the use of N,N'-bisalkanoyl~ethylenediamines independently containing from 8 to 14 carbon atoms in each alkanoyl group and having a particle size from 90 to 150 ~m, preferably from 120 to 140 ~m, as lubricants in polymer-cellulosic fiber compositions.</p> |
