Abstract
A thermoplastic polymer composition reinforced with fibers such as cellulose or other fillers, particularly from natural sources, and a process for manufacturing the composition are disclosed. The polymer is extruded with a salt which reduces the melting point and pelletized. The pellets are then extruded again with the filler. The composition with the filler can then be melted at the reduced melting temperature to manufacture an article.
