Preparation of nylon salts from diamine carbamates and dicarboxylic acids |
摘要 |
Substantially anhydrous nylon salts are made in a solid state process in which solid diamine carbamates are contacted and mixed with solid dicarboxylic acids in a near instantaneous reaction to produce the salt, and preferably are prepared by mixing the solid diamine carbamates and the solid dicarboxylic acids under conditions of high shear. |
