Claims
- 1. In a method for curing a 1,2-epoxy resin wherein an effective amount of an amine curing agent is intimately mixed with the 1,2-epoxy resin under epoxy resin curing conditions, the improvement which comprises using, as the curing agent a Mannich condensate of Formula IV or VI ##STR16## Wherein Q represents --O-- or --NH--,
- n represents a number having an average value of 0 to about 100,
- R represents H or a C.sub.1 to C.sub.4 alkyl group, at least one of R' and R" represents hydrogen and the other represents hydrogen or methyl, and
- Z represents H or an imidazolyl-methylene group having the formula: ##STR17## Wherein: A represents a trifunctional initiator,
- x, y and z represent numbers, and the sum of x+y+z=4 to about 100.
- 2. A method as in claim 1 wherein the Mannich condensate is a Mannich condensate of formula IV.
- 3. A method as in claim 2 wherein Q represents --O--.
- 4. A method as in claim 2 wherein Q represents --NH--.
- 5. A method as in claim 1 wherein the Mannich condensate is a Mannich condensate of formula VI.
