NOVEL (METH)ACRYLIC MONOMER AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a (meth)acrylic monomer which has a high curing rate and is minimized in volume change rate between before and after curing, and to provide a method for producing the same.

SOLUTION: The method for producing a (meth)acrylic monomer represented by formula (I) includes a synthesis process for reacting a specific polyoxyalkylene glycol including one or two 2-4C oxyalkylene structural units with N-hydroxymethyl (meth)acrylamide in the presence of an acid catalyst, wherein R1is hydrogen atom or methyl, R2and R3are each independently 2-4C alkylene, and m and n are integers of 0-50 satisfying m+n≥1.
