HCID 539699792-Methylidene-5-phenylpent-4-enoic acid

Procedure

In a similar manner to that employed for the copolymer (a-2-1), except that the charged amounts of styrene and methacrylic acid were changed to 74.4% by mass and 5.6% by mass, respectively, a styrene-methacrylic acid copolymer (a-2-2) was obtained.
