METHOD OF PRODUCING HYDROPHILIC POLYMER

摘要

In a method of producing a hydrophilic polymer by continuously feeding an aqueous solution 26 of vinyl type monomer onto the upper surface of a movable belt 2 and polymerizing the monomer, the continuous belt 2 is formed with a downwardly projecting flexure portion 100, which is the deepest in the vicinity of polymerizing section for the vinyl type monomer, along the direction of travel of the continuous belt, and the polymerization of the vinyl type monomer is started in the flexure portion. Further, the water vapor volatilizing from the surface of the aqueous solution of vinyl type monomer for which polymerization has been started is expelled.
