ABSTRACT:
Dusty additives intended to be used as stabilizer, lubricants, etc. in a polymer or copolymer of vinylchloride are firstly mixed with said polymer or copolymer of vinylchloride, or of acrylonitrile, or of butadiene or of styrene in granular form, e.g. in the form in which they are rendered by a suspension polymerization process, at a temperature of 167.degree. to 230.degree. F., and then cooled to obtain that these additives come into the granules of polymer or copolymer, retaining the same granulometry of this polymer or copolymer granules, with said additive constituting up to 5/6 of the resulting mixture.
