Process for preparing water-soluble polymers |
摘要 |
Disclosed herein is a process for preparing a water-soluble polymer comprising subjecting an N-vinylcarboxylic acid amide alone or a mixture of the N-vinylcarboxylic acid amide and other water-soluble vinyl compound(s) copolymerizable therewith to suspension polymerization, and adding hydroxylamine followed by acidic hydrolysis. A water-soluble can be polymerized efficiently without forming gel. |
