Process for preparing an acyl-lactam compound |
| 摘要 |
The invention relates to a process for preparing an acyl-lactam compound characterized in that the reaction product of a lactam with a dicarboxylic acid anhydride is reacted with a polyol at a temperature of 150 DEG C. at most. These acyl-lactam compounds are very suitable as activator in the preparation of nylon block copolymers, more specifically in the RIM or RRIM systems.
