The present invention relates to a process for the production of elastic, compact or cellular moldings based on elastomers containing N- benzylurea groups in bound form, by reacting a) one or more organic and/or modified organic polyiso- cyanates with b) N-benzylpolyoxyalkylene-polyamines or mixtures of N-benzylpolyoxyalkylene-polyamines and polyoxy- alkylene-polyamines containing from 2 to 4 primary amino groups and c) one or more alkyl-substituted aromatic polyamines having a molecular weight of up to 500, in the presence or absence of d) catalysts and, if desired, e) blowing agents, f) auxiliaries and/or g) additives, and to the N-benzylpolyoxyalkylene-polyamines and mix- tures of N-benzylpolyoxyalkylene-polyamines and polyoxy- alkylene-polyamines containing from 2 to 4 primary amino groups which can be used for this purpose, and to the elastomers prepared.
