Abstract

The present invention relates to polyaspartates corresponding to the formula ##STR1## wherein X.sub.1 represents the residue obtained by removing the amino groups from a polyether polyamine having a functionality of n and a number average molecular weight of less than 600, wherein the amino groups are attached to primary carbon atoms and the ether groups are separated by at least two carbon atoms, R.sub.1 and R.sub.2 are identical or different and represent organic groups which are inert to isocyanate groups at a temperature of 100.degree. C. or less, R.sub.3 and R.sub.4 are identical or different and represent hydrogen or organic groups which are inert towards isocyanate groups at a temperature of 100.degree. C. or less and n is 2 to 4. The present invention also relates to polyureas prepared by reacting the polyaspartates and optionally other isocyanate-reactive compounds with polyisocyanates.
