| titleOfInvention | Method for producing copolymer |
| abstract | PROBLEM TO BE SOLVED: To provide an organic solvent when copolymerizing a vinyl monomer containing a sulfonic acid (or a salt thereof) group, a vinyl monomer containing a polyalkylene oxide chain having one end etherified, and another vinyl monomer. Without the need for complicated polymerization operations, it is possible to copolymerize all monomers at a high introduction rate, and even after polymerization, does not require complicated processing operations. An advantageous manufacturing method is provided. SOLUTION: As a polymerization initiator, the following general formula (2): A salt of the compound represented by (3) or (4) is used. Embedded image Embedded image Embedded image (Wherein each of R 5 and R 6 ; R 7 and R 8 ; R 9 and R 10; R 11 and R 12; R 1 7 and R 18; and R 19 and R 20, or respectively the (cyclo) alkyl group, Or both of them together represent a divalent aliphatic group. R 13 , R 14 , R 15 and R 16 each represent a hydrogen atom, a (cyclo) alkyl group, an allyl group, a phenyl group or the like. X 1 and X 2 each represent a lower alkylene group or the like. ) |
