Process for producing high-purity vinylpyrrolidone polymer |
| abstract |
A process for producing a high-purity vinylpyrrolidone polymer which dissolves in an organic solvent to give a transparent solution. The process comprises using a redox initiator comprising an organic peroxide and a sulfurous acid salt to polymerize vinylpyrrolidone and bringing the resultant polymer into contact with an anion-exchange resin to purify it. |
