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.
La vitesse d'aminolyse des butyrolactones peut être réglée de manière prévisible par la fixation d'un substituant ayant une valeur d'effet de champ (F) connue à la position alpha avant la mise en réaction du butyrolactone avec une amine. Le produit de l'aminolyse est un gamma-hydroxy amide. Les matières obtenues sont utilisées comme agents de réticulation dans une grande variétés de revêtements et de procédés de revêtement.
