Document Type and Number:
Japanese Patent JP2022118362
Kind Code:
A
Abstract:
To provide a method for producing a neutralized salt aqueous solution of a dialkylaminoalkylene methacrylate which is excellent in storage stability.SOLUTION: In a method for producing a neutralized salt aqueous solution of a dialkylaminoalkylene methacrylate comprising a step to bring the dialkylaminoalkylene methacrylate and a first acid into contact with each other, a molar ratio of an amount (mole) of proton originating from the first acid to a used amount (mole) of the dialkylaminoalkylene methacrylate is more than 1, and pH of the neutralized salt aqueous solution of the dialkylaminoalkylene methacrylate is 2-5.5.SELECTED DRAWING: None
