Abstract
PURPOSE: To prepare a powdery polyacrylamide useful as a coagulant, etc., by polymerizing an aqueous solution containing specific amounts of acrylamide and other water-soluble monomers, in the presence of a reducing inorganic sulfur compound, using a water-soluble azo compound as a polymerization initiator, in a dispersion medium.
CONSTITUTION: The objective polymer is prepared by polymerizing (A) an aqueous solution containing 45W90 wt% of water-soluble vinyl monomers (wherein ≥50 mol% is acrylamide), in the presence of (B) a reducing inorganic sulfur compound (e.g. sodium bisulfite, etc.), (C) a water-soluble azo compound (e.g. 2,2'-azobis-2-amidinopropane di-hydrochloride, etc.) as polymerization initiators, and (D) a dispersion stabilizer, in an organic solvent. The component D is pref. an oil-soluble cellulose ester or cellulose ether.
USE: Thickner, sizing agent, coagulant, paper additives, etc.
