METHOD OF PREPARING HIGH-MOLECULAR CATIONIC WATER-SOLUBLE POLYMER Russian patent published in 1995 - IPC

Abstract RU 2048479 C1

FIELD: cellulose industry. SUBSTANCE: method involves polymerization of 1,2-dimethyl-5-vinylpyridinium methyl sulfate in the presence of oxidative-reducing initiating agent - β-hydroxypropyl-tert.-butyl-peroxide. Polymerization can be realized in the presence of acrylamide and a-amino-g-methylbutyric acid as a mixture of DL-isomers. Method is used in production of water-soluble high-molecular cationic flocculants, for acceleration of condensing and filtration suspension processes in clarification of industrial return water and domestic sewer. EFFECT: improved method of polymer preparing. 3 cl
