TOOLS FOR IMPROVING RETENTION, DRAINAGE AND PROCESSING OF FLUSH-OUT SOLIDS AND USE OF THE TOOLS, IN PARTICULAR IN PAPER MANUFACTURING AND USE OF THE TOOLS |
| abstract |
Basic, water-soluble polymers comprise a reaction prod (C) made by cross linking quaternary N-contg. polyamines (A) made by reacting mono- and/or polyhydric amines with a reaction prod. of sec. amine hydrochlorides and epichlorhydrin, with basic polyaminoamides (B) derived from >=1 dicarboxylic acid and >=1 polyalkylenepolyamine and/or >=1 aminocarboxylic acid or a lactam derived from this, and/or hexamethylenediammonium adipate, using a polyfunctional cpd. such as epichlorhydrin and/or a dihaloalkane. The polymers are esp. used as dewatering and retention aids e.g. in papermaking, and a flocculating agents for industrial waste waters and suspensions. |
