Abstract
A quaternary salt-type reactive polymer composition comprising therein repeating monomer units represented by the following general formula ##SPC1## Wherein R represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms; R.sub.1 represents a hydrogen atom, an alkyl group having 1 to 6 carbon atoms, an alkoxycarbonyl group, having 2 to 8 carbon atoms an aryl group, a carbamoyl group having 1 to 8 carbon atoms, a carboxy group, or an acyl group having 1 to 8 carbon atoms; R.sub.2 represents a hydrogen atom, a methyl group or a cyano group; R.sub.3 represents a hydrogen atom, a carbamoyl group having 1 to 8 carbon atoms, a nitro group, a cyano group, an alkoxy group having 1 to 3 carbon atoms or an alkoxy carbonyl group having 2 to 8 carbon atoms; Y represents a divalent radical having 1 to 12 carbon atoms; and X.sup.- represents a halogen atom, such as Br, Cl or I, an alkanesulfonyloxy group having 1 to 4 carbon atoms, an alkanesulfonyloxy group having 1 to 4 carbon atoms a styrenesulfonyloxy group, or an arylsulfonyloxy group having 6 to 10 carbon atoms. A preferred -Y- moiety is ##EQU1## wherein R.sub.4 represents ##SPC2## Wherein m is 0, 1, 2, or 3; p, q and r is 0 or 1; R.sub.5 represents a hydrogen atom or a methyl group. The quaternary salt-type functional polymer described above can be synthesized by reacting (1) a vinylpyridine with a halide or a sulfonic ester compound containing at least one unsaturated group or (2), a vinyl pyridine unit containing polymer with a halide or a sulfonic ester compound containing at least one unsaturated group, and processes for the preparation thereof.
