Abstract

The invention relates to a process for the production of elastic, compact or cellular moldings based on elastomers containing N-substituted urea and amide groups in bound form, by reacting PA1 a) one or more organic and/or modified organic polyisocyanate with PA1 b) a polyazomethine-containing polyoxyalkylene-polyamine mixture (b) which contains: PA1 bi) one or more polyoxyalkylene-polyaldimine and/or polyketimine, PA1 bii) one or more polyoxyalkylene-polyamine containing terminal secondary amino groups, and, if desired, PA1 biii) one or more polyoxyalkylene-polyamine containing terminal primary amino groups and PA1 c) one or more alkyl-substituted aromatic polyamine having a molcular weight of up to 500, in the presence or absence of PA1 d) catalyst, and, if appropriate, PA1 e) blowing agents, PA1 f) auxiliaries and/or PA1 g) additives, to polyazomethine containing polyoxyalkylene - polyamine mixtures which can be used for this purpose and to the prepared elastomers.
