Abstract

Polyenamine resins useful as adhesives and in coating applications are produced from the reaction of polyacetoacetates or polyacetoacetamides with blocked polyamines. The blocked polyamines are ketimines or enamines obtained by the reaction of an amine or amide with either a ketone or an aldimine obtained by the reaction of an amine or amide with an aldehyde.

Claims

2. The method as claimed in claim 1, wherein the polyenamine contains units of the formula:

wherein R'"'"''"'"' is alkylene, cycloalkylene, arylene, arylalkylene, cycloalkylalkylene, alkylcycloalkylene, alkylarylene or the ethers thereof of from one to 50 carbon atoms, R'"'"''"'"''"'"''"'"' is hydrogen or alkyl of from one to six carbon atoms and n has a value of from 1 to 3, R represents the base residue of the polyacetoacetate or polyacetoacetamide and X is oxygen or nitrogen.

3. The method as claimed in claim 1, wherein acetone is added as a solvent in step (ii).

4. The method as claimed in claim 1, wherein the polyamine is bis(6-aminohexyl)ether, the carbonyl-containing compound is methyl ethyl ketone and the polyacetoacetate is trimethylolpropane trisacetoacetate.

5. The method as claimed in claim 1, wherein the polyamine is 1, 6-hexanediamine, the carbonyl-containing compound is methyl etHyl ketone and the polyacetoacetate is trimethylolpropane trisacetoacetate.

6. The method as claimed in claim 1, wherein the polyamine is 1, 6-hexanediamine, the carbonyl-containing compound is methyl ethyl ketone and the polyacetoacetate is the polyester triol of trimethylolpropane and epsilon-caprolacetone having an average molecular weight of about 540.
