Patent ID: 7731880

Claim:
A method for forming a composition comprising: (i) combining (a) from about 1 to about 8 weight percent of a fatty acid bis-amide of the structure: where R 1 and R 2 are independently saturated or unsaturated linear hydrocarbyl groups containing from 11 to 35 carbon atoms, (b) from about 0.25 to 0.75 weight percent of an inorganic particulate that is finely powdered pumice having a particle size of 50 μm or less, (c) from about 10 to about 90 weight percent of a cellulosic particulate from about 1 mm to about 100 μm in length, (d) from about 90 to about 10 weight percent of a thermoplastic; and, (e) from about 0.2 to about 10 weight percent of a coupling agent for coupling cellulosic particulate (c) to thermoplastic (d); and, (ii) extruding the composition through an extruder to provide cellulosic-thermoplastic composite, wherein no lubricants comprising zinc stearate are combined with components (a)-(e).
