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

Procedure

Styrene methacrylic acid copolymer was prepared by using the same procedures as in Example 1 except 67 parts of styrene and 3 parts of methacrylic acid was used in place of 70 parts of styrene. The resulting copolymer had a number average molecular weight of 3,800, a glass transition temperature of 70° C., and a non-volatile content of 99.8%.
