Abstract
Poly-(-2-aminoalkyl)polyamine compounds are provided having the following formula: ##STR1## wherein: n is an integer of from 3 to about 12; R.sub.1 is selected from H and an alkyl group containing from 1 to about 10 carbon atoms; R.sub.2 and R.sub.3 are each independently selected from H and a lower alkyl group containing from 1 to about 6 carbon atoms; R.sub.4 is selected from H and ##STR2## R.sub.5 is selected from an alkyl group containing from about 6 to about 25 carbon atoms.
Claims7
An epoxy resin composition comprising an epoxy resin and at least one epoxy resin curing agent of the formula:
- ##STR14## wherein:
- n is an integer of from 3 to about 12;
- R.sub.1 is selected from H and an alkyl group containing from 1 to about 10 carbon atoms;
- R.sub.2 and R.sub.3 are each independently selected from H and a lower alkyl group containing from 1 to about 6 carbon atoms;
- R.sub.4 is selected from H and ##STR15## R.sub.5 is selected from an alkyl group containing from about 6 to about 25 carbon atoms.
In a method for curing an epoxy resin composition comprising incorporating an epoxy resin curing agent into an epoxy resin and heating the combination of the epoxy resin and the epoxy curing agent, the improvement which comprises said epoxy resin curing agent being represented by the formula:
- ##STR19## wherein:
- n is an integer of from 3 to about 12;
- R.sub.1 is selected from H and an alkyl group containing from 1 to about 10 carbon atoms;
- R.sub.2 and R.sub.3 are each independently selected from H and a lower alkyl group containing from 1 to about 6 carbon atoms;
- R.sub.4 is selected from H and ##STR20## R.sub.5 is selected from an alkyl group containing from about 6 to about 25 carbon atoms.
