ABSTRACT:
N-Cyanoacylamide compounds of the formula I ##STR1## wherein R.sub.1 is hydrogen, alkyl, cycloalkyl or aryl, R.sub.2 is hydrogen or alkyl and R.sub.3 is alkylene or arylenealkylene, are prepared by reacting 1 mol of an N-cyanocarboxylic acid amide salt with 1 mol of a halogen compound in a polar, aprotic solvent.
The N-cyanoacylamide compounds of the formula I can be used for hardening epoxide resins, for the preparation of isomelamine or for the preparation of linear polymers which can be crosslinked by heat.
