ABSTRACT:
Aziridinyl-terminated polymers containing the recurring unit ##STR1## wherein R.sub.1 is hydrogen or methyl and R.sub.2 is hydrogen or a side chain of like structure, are prepared by warming N-(2-hydroxyethyl)- or N-(2-hydroxypropyl)ethylenimine or -propyleneimine. Generally, the reaction is conducted in the presence of an alkali metal and at least trace amounts of water. The polymers are useful as curing agents for epoxy resins.
