Method for producing anhydrous polyaspartic acid |
| abstract |
(57) [Summary] (Modified) [Objective] To provide a method for producing high molecular weight anhydrous polyaspartic acid in an industrially feasible manner and in a short time. [Structure] An acid catalyst was added to 1 mol of aspartic acid. After being mixed in a proportion of 001 to 0.3 mol, the mixture is subjected to polycondensation reaction in a reactor within a temperature range of 100 to 350 ° C. while stirring or kneading, and a method for producing polyaspartic acid anhydride. . |
