Abstract

PURPOSE: To obtain an acrylamide polymer suitable for a soil conditioner, a coagulant for water treatment, a thickening agent, etc., having a molecular weight, improved water-solubility and coagulating effect, by polymerizing acrylamide monomers in the presence of a carbamic acid compound using an azo catalyst.
CONSTITUTION: A) Preferably a 5-30 per cent aqueous solution of acrylamide or its mixture with comonomers (e.g. acrylic acid, etc.), is prepared. B) A water- soluble azo catalyst (e.g. 4,4'-azobis-4-cyano-valeric acid, etc.), preferably 0.005-0.1 wt.% based on the monomers is added to the aqueous solution thus obtained. C) A compound of carbamic acid (e.g. ammonium carbamate) in an amount of 0.01-1 wt.% based on the monomers is added to the resulting solution, which is polymerized preferably at 15W45°C to give the desired acrylamide copolymer
