Abstract: PROBLEM TO BE SOLVED: To provide an improved method for manufacturing a polyvinyl pyrrolidone.
SOLUTION: In the method for manufacturing the polyvinyl pyrrolidone by a polymerization initiated by a free radical in the presence of an initiator, the polymerization is carried out by spray polymerization or droplet polymerization. The initiator to be used is an organic or inorganic peroxide, a hydroperoxide, a persulfate, an azo compound, a photo-initiator or a redox initiator. The polymerization is carried out in a water solution at a polymerization temperature of 70-250°C by forming and spraying droplets in an inert gas flow or forming droplets and carrying out the polymerization in a spray tower.
