Abstract:
The present invention relates to a process for organocatalytic ring-opening polymerization of at least one monomer M suitable for ring-opening polymerization, or of mixtures thereof, wherein, in a step (i), at least one N-heterocyclic compound is subjected in the presence of at least one Zerevitinov-active compound Z1 to a temperature of at least 80° C. for a period of at least 30 seconds and, in a step (ii), the monomer M is added and reacted.
