ABSTRACT:
The invention relates to a process for producing a powder of a cationic polymer by spreading on a moveable carrier a layer of an aqueous solution of a vinyl monomer, carrying out continuous polymerization followed by peeling off hydrous polymer from the carrier in a hot state, and cutting said hydrous polymer in a hot state by a shearing stress.
