Alkylation of diamines and polyamines by allyl and methallyl chlorides or by chloropropenes has been used to obtain polyalkylpolyamines that had not been described previously.The alkylation of the polyamines by allyl and methallyl chlorides proceeds more energetically in comparison with the alkylation by ethyl chloride or chloropropenes.The alkylation of either cyclic and acyclic polyamines begins with the primary amino group.With increasing length of the chain and the alkyl radical at the nitrogen of the alkylated polyamines, their capability for reacting with the evolved hydrogen chloride drops off, and this leads to a decrease in yield of the desired products owing to the loss of activity of the original or partly alkylated polyamines.
