ABSTRACT:
A process for preparing N-alkenylureas of the general formula I ##STR1## where R.sup.1 and R.sup.2 are hydrogen, C.sub.1 - to C.sub.40 -alkyl, C.sub.2 - to C.sub.40 -alkenyl, C.sub.3 - to C.sub.20 -cycloalkyl, C.sub.4 - to C.sub.20 -alkylcyc1oalkyl, C.sub.4 - to C.sub.20 -cycloalkylalkyl, aryl, C.sub.7 - to C.sub.20 -alkylaryl or C.sub.7 - to C.sub.20 -aralkyl, or aryl, C.sub.7 - to C.sub.20 -alkylaryl or C.sub.7 - to C.sub.20 -aralkyl which are mono- to pentasubstituted by C.sub.1 - to C.sub.8 -alkyl, C.sub.1 - to C.sub.8 -alkoxy or halogen, together are a C.sub.2 - to C.sub.10 -alkylene chain which is unsubstituted or mono- to hexasubstituted by C.sub.1 - to C.sub.8 -alkyl, and
