Zusammenfassung:A process is disclosed for producing a blend of chlorinated low density polyethylene and chlorinated high density polyethylene wherein the polyethylenes are placed in a solvent and the temperature raised to a point where the low density polyethylene goes into solution and the high density polyethylene does not go into solution. The low density polyethylene is chlorinated up to the desired level and then the temperature is raised to dissolve the high density polyethylene and chlorination of both polyethylenes is continued to the desired level.
