Production process for glyoxylic acid (salt)-based polymer |
摘要 |
The present invention provides a production process for a terminal-end-stabilized glyoxylic acid (salt)-based polymer, which process enables to reduce the amount of the polymerization solvent, as recovered or removed after the end of the polymerization (before the start of the hydrolysis) or after the end of the hydrolysis, without lowering the production efficiency. The production process for a terminal-end-stabilized glyoxylic acid (salt)-based polymer comprises the step of polymerizing a monomer component including a glyoxylic acid ester in order to produce the terminal-end-stabilized glyoxylic acid (salt)-based polymer, wherein a terminal end stabilizer is used as a reaction medium of the polymerization.
