PCT No. PCT/CH82/00135 Sec. 371 Date Aug. 6, 1984 Sec. 102(e) Date Aug. 6, 1984 PCT Filed Dec. 20, 1982 PCT Pub. No. WO84/02530 PCT Pub. Date Jul. 5, 1984.Processes for continuous conversion of granulated PVC material and additive substances to free-flowing pre-blends mechanically intermix at room temperature granulated PVC material and additive substances in a first zone continuously transversed thereby to provide a macroscopically homogeneous admixture thereof. The additive substances are melted in a subsequent second zone and the molten additive substances are absorbed with the granulated PVC material in a subsequent third zone to provide the free-flowing pre-blend. This pre-blend advantageously may be passed through a second set of three zones corresponding to the mentioned first, second and third zones.
