Method for producing polyvinylimidazoline |
| abstract |
(57) [Summary] [PROBLEMS] A conventional method for producing polyvinyl imidazoline comprises: It was not easy to change the molecular weight and it was not industrially satisfactory. SOLUTION: In a method for producing polyvinylimidazoline or a salt thereof by reacting a polymer containing a nitrile group with a polyamine, the molecular weight of polyvinylimidazoline is controlled by changing the reaction temperature. |
