There is disclosed a class of N-alkylpolyamines and their use as curing agents for epoxy resins, and in particular to such polyamines having the formula R--[NH(CH 2 ) x ] y --NHR' where R is an aliphatic hydrocarbon radical having from 5 through 8 carbon atoms, R' is H, R or R", x is an integer of 2 or 3 and y is an integer of 2-4. A monoepoxide adduct of the monoalkyl substituted polyamine is also disclosed wherein R" may then become an aliphatic substituent (2-14 carbon atoms) which may contain (a) an oxygen atom, (b) a hydroxyl group or (c) an aromatic substituent such as a phenyl ring. |
