Abstract

Copolymeric poly-anions of formula (I) are prepd. by radical copolymerisation of a 1:1 mixt. of the monomers in an oxygen free organic solvent in the presence of a radical producing initiator, at 60-70 deg.C for 3-5 hrs. The prod. is purified pref. by extn. with benzene or chloroform, and opt. transformed into acid, amide or ehter. The concn. of comonomers is 2-3 mole per litre. - In the formula X+ = H, alkali-metal or an organic cation, R = -OH, -OR', -SR' or -NR'R'', R' = alkyl, alkenyl or alkinyl, aryl or a heterocyclic qp., R'' = H or R'.
