Abstract
PURPOSE: To prevent the decomposition of acrylamide polymer useful as a setting agent and an additive for electrolytic refining, by adding a specific mercaptobenzimidazole derivative to an acrylamide polymer.
CONSTITUTION: 100 Parts by weight of an acrylamide polymr is mixed with about 0.1W20 parts by weight of a 2-mercaptobenzimidazole drrivative of formula (R1W4 are methyl or ethyl, X is H, alkali metal, or ammonium), and homogenized with a mixer, blender, etc. The aqueous solution of the acrylamide polymer composition thus stabilized, is stable even at a low temperature or at a temperature as high as 80°C. The acrylamide polymer includes a homopolymer of acrylamide, a copolymer containing acrylamide as major component, or their mixture.
