Process for drying chlorinated polymers

摘要

Chlorinated polymers obtained by a filter-separation procedure, in a moist form, especially a water-containing moist form, are dried. To this end, the moist polymer is predried in a first fluidized-bed drying zone, this being continuously operated, and is thereafter further dried in one or more further fluidized-bed drying zones disposed downstream, of the said first drying zone.
