Preparation and use of gamma-butyrolactones as cross-linking agents

   
   

The rate of aminolysis of butyrolactones is predictably adjusted by attaching a substituent having a known field effect value (F) to the alpha position before reacting the substituted buytrolactone with an amine. The aminolysis product is a gamma-hydroxy amide. The resulting materials are useful as the cross-linking agents in a variety of coatings and coatings processes.

El índice del aminolysis de butyrolactones fiable es ajustado uniendo un sustituto que tiene un valor sabido del efecto del campo (f) a la posición de la alfa antes de reaccionar el buytrolactone substituido con una amina. El producto del aminolysis es una amida gamma-gamma-hydroxy. Los materiales que resultan son útiles como los agentes del cross-linking en una variedad de capas y de procesos de las capas.
