Abstract
PURPOSE: To obtain a water-soluble cationic polymer having a high molecular weight in a short polymerization time, by polymerizing a methacrylic or acrylic ester in an aqueous solution in the presence of a specific polymerization initiator and a metallic salt.
CONSTITUTION: A salt, e.g. a sulfate, of a metal selected from the group consisting of iron, copper, tin(II), manganese and cerium in an amount of preferably 0.1W 300ppm based on a monomer is added to an aqueous solution of the monomer, e.g. dimethylaminoethyl acylate, expressed by the formula (R1 is H or methyl; R2 is H, methyl or ethyl; R3 and R4 are methyl or ethyl; A is ethylene, etc; X is electronegative group capable of forming a salt with an ammoniacal nitrogen). The mixture is then polymerized in the presence of preferably 100W6,000ppm 2,2'-azobis(2- amidinopropane)dihydrochloride as a polymerization initiator and preferably 10W 300ppm(acidic) sodium sulfite at 15W50°C to give the aimed water-soluble cationic polymer.
