Abstract
Polymeric compositions containing amide acetal groups are crosslinked by hydrolyzing the amide acetal groups, and the hydroxyl groups and/or the amines functions that are formed are reacted to crosslink the composition.
Claims32
A composition, comprising,
- (a) (i) a first polymer having at least one intact amide acetal groups attached to a molecule of said first polymer;
- (ii) a crosslinking agent containing first functional groups which react with hydroxyl groups or secondary amines, provided that said crosslinking agent has an average of at least two first functional groups per molecule of said crosslinking agent;
- (iii) optionally at least one solvent;
- and
- (iv) optionally at least one catalyst for the reaction of said hydroxyl groups or secondary amines with said first functional groups;
- and at least one second catalyst for hydrolysis of said amide acetal groups;
- and
- (b) (i) a second polymer having second functional groups which react with hydroxyl groups or secondary amines, provided that said second polymer has an average of at least two second functional groups per molecule of said second polymer;
- (ii) a compound containing at least one intact amide acetal group;
- (iii) optionally at least one solvent;
- and
- (iv) optionally at least one first catalyst for the reaction of said hydroxyl groups or secondary amines with said second functional groups;
