Method for producing modified polyvinyl alcohol |
| abstract |
(57) Abstract: A method for producing a modified polyvinyl alcohol by reacting polyvinyl alcohol with a vinyl compound, the product having a high effective utilization rate of the vinyl compound to polyvinyl alcohol and no coloring, Also provided is a method for producing a modified PVA that produces less by-products. A liquid basic catalyst is added to powdered polyvinyl alcohol to produce an alcoholated polyvinyl alcohol, a vinyl compound is added to the alcoholated polyvinyl alcohol, and a Michael addition reaction is performed under solid-liquid reaction conditions. |
