| titleOfInvention | Process for producing carboxyl group-containing copolymer |
| abstract | A method for producing a carboxyl group-containing copolymer capable of efficiently producing a polymer having a desired weight average molecular weight is provided. A monomer component comprising an unsaturated carboxylic acid monomer (A) and a polyalkylene glycol monomer (B) forming the structural unit (b) represented by the formula (1) is provided. And a step of polymerizing using a chain transfer agent containing a phosphorus atom-containing compound. In the polymerization step, a polymerization initiator may be used in the polymerization reaction. Of the carboxyl group-containing copolymer in which at least 50% of the polymerization initiator is added at the reaction temperature of 70 to 90 ° C. Production method. (R 1 to R 3 are each independently H, methyl group; (AO) is an oxyalkylene group; n is an integer of 2 to 80; x is an integer of 0 to 2; y is 0 or 1) [Selection figure] None |
