Abstract
PURPOSE: To improve the stability of the titled monomer useful as a raw material of textile modifier, water treating agent, etc., without lowering its polymerization reactivity, by adding a copper compound to the cationic vinyl monomer.
CONSTITUTION: A cationc vinyl monomer of formula (R1 is H or CH3; R2 and R3 are 1W4C alkyl or 2W4C hydroxyalkyl; R4 is H, 1W4C alkyl, etc.; A is O or NH; B is 1W4C alkylene or 2W4C hydroxyalkylene; X is anionic counter ion) is stabilized by adding a copper compound thereto. The copper compound is, e.g. cupric chloride, cupric sulfate, etc., and its amount is 0.01W5,000ppm as copper ion based on the monomer of formula. The addition of the copper compound results in the prevention of the degradation of the monomer during storage, transportation or preparation and the remarkable improvement of the stability without lowering the polymerization reactivity of the monomer.
