| titleOfInvention | Method for purifying (meth) acrylic acid ester and method for producing (meth) acrylic acid ester polymer |
| abstract | Kind Code: A1 A method for purifying (meth) acrylic acid ester and a purified (meth) acrylic acid ester that can remove various coloring-causing substances resulting from coloring of molded articles at low cost using inexpensive and simple equipment. The manufacturing method of the (meth) acrylic acid ester polymer excellent in transparency which polymerizes the monomer containing this is provided. A method for purifying a (meth) acrylic acid ester by contacting a (meth) acrylic acid ester with a cation exchange resin, wherein the cation exchange resin is 1 volume relative to the empty space of the cation exchange resin. A method for purifying a (meth) acrylate ester and a purified (meth) acrylate ester in which the absorbance (β) of the alcohol after washing the cation exchange resin with twice the amount of alcohol satisfies the requirement of 1 or less The manufacturing method of the (meth) acrylic acid ester polymer which polymerizes the monomer containing. [Selection figure] None |
