Polyacrylonitriles with a low K value, a process for their preparation and their suitable use |
| abstract |
A method of inhibiting scale formation or precipitation in an aqueous alkaline-earth salt solution with an aqueous solution of a hydrolyzed polyacrylonitrile salt made by heating homopolymers and copolymers of acrylonitrile with very low Fikentscher K values of 34-15 and a total content of sulfonate and sulfate end groups, which do not originate from correspondingly substituted comonomers, of 250 to 1,000 milliequivalents per kilogram of polymer, 180 to 900 milliequivalents per kilogram being in the form of sulfonate end groups, and to suitable semi-continuous or continuous precipitation polymerization process for their preparation by means of a redox system in an aqueous medium. |
