ABSTRACT:
The disclosure relates to a process for making fine particulate, non-agglomerating chloropolyethylene by subjecting pulverulent polyethylene to a chlorination reaction in aqueous or aqueous/hydrochloric acid-suspension with chlorine gas at a temperature of about 20.degree. to 140.degree. C. in the presence of silicic acid and silicon oil, separating, washing and drying the chloropolyethylene. More particularly, the disclosure provides for the chlorination to be terminated and for the aqueous hydrochloric acid-suspension of chloropolyethylene to be then intensively mixed with an aqueous or aqueous/hydrochloric acid-dispersion having talc as well as an orthophosphoric acid mono- and/or diester or a polysiloxane by means of an emulsifier dispersed in it, and for the chloropolyethylene to be separated from the mixture, to be washed and dried.
