PROBLEM TO BE SOLVED: To provide a wood-filled thermoplastic resin which is retarded in aging when exposed to weathering, having an improved dimensional stability due to water absorption, and having high productivity by an extruder. SOLUTION: The filler is coated with a wax using the natural wax or the synthetic wax as the lubricants for a filler-filled synthetic resin, so that productivity and resistance to water absorption are improved. The natural wax is selected from petroleum wax, montan wax, animal wax, and vegetable wax. The synthetic wax is selected from a fatty acid, fatty acid ester fatty acid amides, Fischer-Tropsch wax, polyolefin wax, and polar-modified polyolefin waxes. COPYRIGHT: (C)2006,JPO&NCIPI
