PURPOSE:To readily obtain the above polymer by reaction between a polymer having amino group in the side chain, carbon disulfide and a basic substance to produce a polymer having dithiocarbamate in the side chain followed by reaction of a haloacetate. CONSTITUTION:A reaction is carried out between (A) a polymer having amino group in the side chain (e.g., homopolymer or copolymer of allylamine, 2- aminoethyl acrylate), (B) carbon disulfide, and (C) a basic substance (e.g., ammonia water) to produce a polymer having dithiocarbamate in the side chain followed by reaction of a haloacetate to obtain the objective polymer having rhodamine ring in the side chain. According to the above process, rhodanine ring-contg. polymers useful as intermediates for various functional polymers can be produced with a small number of steps, also at room temperature in a yield of >=87mol.%. |
