Abstract
Described in this invention is a catalytic process for making amide acetals from nitrites and diethanolamines. Amide acetals can be further crosslinked by hydrolyzing the amide acetal groups, and subsequently reacting the hydroxyl groups and/or the amine functions that are formed, to crosslink the composition.
