摘要：
Oligomeric cyanoguanidines of formula I ##STR1## wherein, for example, R.sup.1 and R.sup.2 are each phenyl, R is 1,4-phenylene and n is an integer from 1 to 20, are suitable latent hardeners for epoxy resins. They are readily soluble in solvents suitable for the application of epoxy resins, and the cured products obtained therewith have a high glass transition temperature.
