Abstract

PURPOSE: To suppress rise of viscosity and spinnability of a flocculant even in the case of high molecular weight and yet to exert superior flocculation effect, by adding a cationic organic polymer of a specified quat. ammonium salt type with divalent or higher-valent anions introduced as ion pairs.
CONSTITUTION: The flocculant contains ≥1 kinds of cationic organic polymers of a quat. ammonium salt quat. phosphonium salt, or quat. sulfonium salt type, with divalent or higher-valent anions introduced as ion pairs. As said divalent or higher- valent anions, ≥1 kinds of groups of solfuric, carbonic, orthophosphoric, pyrophosphoric, tripolyphosphoric, oxalic, maleic, citric, EDTA, NTA, or low molecular weight polyacrylic or polymaleic acid are preferable. As said cationic organic compound, a (meth)acryloyl oxyalkylammonium salt or the like, vinylphosphonium salt or the like, or benzylsulfonium salt or the like is preferable.
