DRYING SOLID POLYMER

摘要

Solid polymer of an alpha monoolefin having two to eight carbon atoms in the molecule which is wet with a diluent is dried by forming the wet polymer into a slurry with heated aqueous liquid and then drying the polymer by subjecting the slurry to centrifugal force in the dewatering portion of a drying zone to remove substantially all of the aqueous liquid and diluent and then completing the drying operation in the second portion of the drying zone by heating same to a sufficient temperature while continuing to subject the polymer to centrifugal force.
