| titleOfInvention | Method for producing (meth) acrylic acid polymer |
| abstract | [PROBLEMS] To continuously widen the molecular weight distribution of a (meth) acrylic acid-based polymer obtained without performing washing in each batch when performing a polymerization reaction in a batch system. Provided is a method for producing a (meth) acrylic acid polymer that can suppress the generation of 3-sulfopropionic acid during polymerization even when bisulfite is used as a transfer agent. The method for producing a (meth) acrylic acid polymer according to the present invention comprises continuously polymerizing a monomer component containing (meth) acrylic acid in the presence of bisulfite in a batch system ( A method for producing a meth) acrylic acid polymer, wherein at least the second batch and thereafter, inorganic acid is polymerized by the polymerization reaction system by the time when 25% by mass of the total amount of the (meth) acrylic acid is added. Add inside. [Selection] Figure 1 |
