Abstract

PURPOSE:To inhibit spontaneous polymerization of a cationic vinyl monomer and to prevent the coloring of the monomer and its polymer by adding a small amount of oxalic acid, citric acid, malic acid, condensed phosphoric acid, or their salt as an inexpensive stabilizer. CONSTITUTION:A stabilizer comprising oxalic acid, citric acid, malic acid, condensed phosphoric acid (e.g. triphosphoric acid, pyrophosphoric acid, trimetophosphoric acid), or their salt (e.g. alkali metal salt, ammonium salt, water-soluble amine salt) is added into >=50wt% aqueous solution of a cationic vinyl monomer of the formula (R1=H, CH3; R2=CH2CH2 etc.; R3, R4=CH3, CH2CH3; R5H, CnH2n+1, etc.; X<->=Cl<->, Br<->, etc.) to inhibit spontaneous polymerization of the monomer efficiently. The amount of the stabilizer added is 0.1-5,000ppm to the corresponding monomer. This can be applied to the preparation process of the monomer. USE:A starting material of cationic polymers (clarifier of waste water from factories, dehydrating agent of sludges, paper strength improving agent etc.).
