CONTINUOUS SOLUTION POLYMERISATION TO WATER-CONTAINING CROSS-LINKED GEL POLYMER

摘要

A method for the continuous production of a cross-linked polymer, comprising the steps of continuously feeding the aqueous solution of a monomer capable of being converted by aqueous solution polymerization into a watercontaining cross-linked gel polymer and a polymerization initiator to a vessel provided with a plurality of mutually parallel rotary stirring shaft each fitted with stirring blades, finely dividing a water-containing gel polymer issuing from the polymerization in progress by the shearing force of stirring blades generated by the rotation of said stirring shafts while allowing the radical aqueous solution polymerization to proceed without interruption, and continously discharging the resultant finely divided water-containing gel polymer out of said vessel.
