Production method for amide group-containing monomer

Use of an amide group-containing alcohol having a total amount of Na, K, and Li present as impurities of 300 ppm or less, in a method for producing an amide group-containing monomer comprising conducting a transesterification reaction to obtain an amide group-containing monomer represented by the following formula:

• CH2═C(—R11)C(═O)O—Y1—NHC(═O)—R12
• wherein
• R11 is a hydrogen atom, a monovalent organic group or a halogen atom,
• Y1 is a divalent to tetravalent hydrocarbon group having 1 to 6 carbon atoms, and
• R12 is a monovalent hydrocarbon group having 6 to 40 carbon atoms,
• from an amide group-containing alcohol represented by the following formula:
• HO—Y1—NHC(═O)—R12
• wherein
• Y1 is a divalent to tetravalent hydrocarbon group having 1 to 6 carbon atoms, and
• R12 is a monovalent hydrocarbon group having 6 to 40 carbon atoms.

An amide group-containing monomer represented by the following formula:

• CH2═C(—R11)C(═O)O—Y1—NHC(═O)—R12
• wherein
• R11 is a hydrogen atom, a monovalent organic group or a halogen atom,
• Y1 is a divalent to tetravalent hydrocarbon group having 1 to 6 carbon atoms, and
• R12 is a monovalent hydrocarbon group having 6 to 40 carbon atoms,
• wherein an amount of a Michael addition product present as an impurity in the amide group-containing monomer is 2% by weight or less relative to the amide group-containing monomer.
