Acrylic acid copolymers

摘要

Prodn. of copolymers whose chains consist alternatingly of acrylic acid and comonomers is characterised in that corresponding maleic anhydride copolymers are converted in aqueous soln. into monoalkali salts and decarboxylated at 120-300, pref. 150-200 degrees C. This is followed by acid treatment in order to precipitate the copolymer.
