Flocculation of suspended solids in aqueous medium by action of cyclo-1,1-diallylgrianidine polymer

摘要

Water-soluble polymers are prepared by homopolymerizing 1,1-diallylguanidine or by copolymerizing 1,1-diallylguanidine. The resulting polymers are cationic and are flocculating agents. When glyoxylated (by reaction with glyoxal) they are water-soluble cationic thermosetting wet strength agents for paper. Wet strength paper containing this polymer rapidly loses its wet strength on normal weathering.
