Abstract: A mixture to be used making an extruded resin article, specifically extruded polyvinyl chloride pipe, and a method of preparing this mixture are disclosed herein. The mixture includes a resin, specifically polyvinyl chloride (PVC), in particulate form and a nonresinous filler material, for example, calcium carbonate, also in particulate form dispersed throughout the PVC. The particles of filler material are adhered to adjacent PVC particles to reduce segregation of the two types of particles. The method by which these particles are adhered to each other includes the use of a second resin which is also in particulate form and which has a lower melting point than that of the PVC resin.
