Abstract
Disclosed herein are tricyclic and pentacyclic polyamines having a secondary or tertiary amine group on an amine functional substituent and at least one primary amine group on each of two amine functional substituents in the molecule. These compounds function excellently as non-visibly carbonating epoxy curing agents and in addition unlike most other amines exhibit a mild amine odor.
Claims12
A process for curing a polyamine of the formula:
- ##STR4## wherein the above formula m is equal to 0 or 1;
- x and y are selected from the group consisting of:
- --CH.sub.2 NH.sub.2 ;
- --CH.sub.2 NH(CH.sub.2 CHR.sub.4 CH.sub.2 NH.sub.2);
- and
- --CH.sub.2 N(CH.sub.2 CHR.sub.4 CH.sub.2 NH.sub.2).sub.2, and mixtures thereof,
- wherein R.sub.1, R.sub.2, R.sub.3, and R.sub.4 are hydrogen or methyl and mixtures thereof, provided that both x and y may not be CH.sub.2 NH.sub.2 comprising contacting the amine with an epoxy resin.
