ABSTRACT:
Resins which comprise polymers which contain multiple acetal groups have been developed which are useful for crosslinking and adhesion promotion in coating and adhesive applications. The polymers which make up these resins are prepared by the addition of aminoacetals to polymers containing anhydride functionality. The polymers are modified by titration with a tertiary amine or alkali base.
