ABSTRACT:
Poly(thio) ethers having terminal amino groups, said ethers having the formula: ##STR1## wherein X is oxygen or sulfur and R stands for a group of the formula ##STR2## wherein R.sub.1 to R.sub.4 represent hydrogen or halogen and B stands for a divalent polyalkylene ether group or a polyalkylene thioether group or mixtures thereof such as is obtained by removal of the hydroxyl or mercapto groups from a polyalkylene ether diol or a polyalkylene thioether dithiol of a molecular weight of 100 to 15000. A process for the production and application is also disclosed. These ethers are used in the production of poly ureas having increased thermal stability and improved tensile and structural strength.
