<p><P>PROBLEM TO BE SOLVED: To provide a method for producing a carboxylic acid monomer with a slight halide content by using an easily available carboxylic acid compound and (meth)acrylic anhydride as raw materials. <P>SOLUTION: A carboxylic acid monomer such as 2-(methacryloyloxy)acetic acid, 2-(methacryloyloxy)propionic acid or 2-(methacryloyloxy)-2-phenylacetic acid is produced by reaction between the corresponding carboxylic acid compound having OH, SH or NH<SB POS="POST">2</SB>group and (meth)acrylic anhydride. In this case, an OH-bearing carboxylic acid compound to be used is preferable as a raw material. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
