    Abstract: Copolymers of cpds. of formula CH2=CH-S-C-R' where R' is H or a (cyclo) aliphatic, araliphatic or aromatic residue with up to 7 C-atoms and vinyl cpds. of formula CHR"=CH"' R"" where R" and R"' are H or methyl and R"" is a carbamide grp. which is bonded to the vinyl grp. either via the N-atom or the carbamyl-C-atom, and may also carry up to 6 aliphatically bonded C-atoms and not more than one hetero atom. The copolymer contains up to 50 wt. % vinylthiocarboxylic acid ester e.g. vinylthioacetate. The products are water-soluble independent of the pH value, and may be saponified, in aqueous soln. at room temp. by NH3 or amines. The solns. are storable over long periods.
