Abstract
PURPOSE: To obtain title polymer particle, excellent in transparency etc., by polymerization in suspension under specified conditions by means of a polymerizer equipped with a stirrer.
CONSTITUTION: Suspension polymerization is carried out, in an aqueous medium, in the presence of a dispersant, a dispersion aid, etc., by use of a polymerizer, which is roughly cylindrical, and equipped with a stirring blade 1 and with buffles 2 having fingers 3, placed above half the liquid level H in the cylindrical part. Wherein purpose polymer particle is obtained by polymerization under such conditions that the ratio of U, mm/sec, circumferential velocity of the tip of the blade 1 to θc, sec, circulation time of the bluid in the vessel is 20W80mm/sec2.
