    • This invention concerns polyiminoethers of general formula (I) in which A is an aliphatic, aromatic or araliphatic group containing 4 to 40 carbon atoms and n free valencies at various carbon atoms, x may assume values of 0 to 40, n has a value of 2, 3 or 4, Z is either a direct bond or the group CR.sup.5 R.sup.6, the substituents R.sup.1 to R.sup.6 independently of one another are H, alkyl or aryl containing up 8 carbon atoms, the substituent R.sup.7 is hydrogen, methyl or ethyl and Q is a phenylene group, which may be substituted by one or two methyl groups, or the group --CHR--M--, where R is selected from the group consisting of H, alkyl or alkenyl and M is selected from the group consisting of alkylene, alkenylene, arylene and alkarylene, and the parts R and M of the molecule independently of one another contain 0 to 12 carbon atoms and, in addition, may be substituted by a C.sub.1-3 alkoxy group. These compounds are made from polyisocyanates of formula A(NCO).sub.n and cyclic monoiminoethers containing hydroxyl groups and are suitable for subsequent processing to polymers.
