    Abstract: 2,2'-Dimorpholinodiethyl ether is produced by reacting diethylene glycol with ammonia under pressure at elevated temperature in the presence of hydrogen. The active hydrogenation catalyst, before reduction with hydrogen, contains 20-85 wt.% alumina, zirconium dioxide, titanium dioxide and/or silica, 1-70 wt.% copper oxide (CuO), less than 20 wt.% nickel oxide with respect to CuO and 0-50 wt.% other metal oxide(s). In the production of 2,2'-dimorpholinodiethyl ether (DMDEE) by reacting diethylene glycol with ammonia under pressure at elevated temperature in the presence of hydrogen and a hydrogenation catalyst, the active catalyst, before reduction with hydrogen, contains 20-85 wt.% aluminum oxide (Al2O3), zirconium dioxide (ZrO2), titanium dioxide (TiO2) and/or silica (SiO2), 1-70 wt.% copper oxide (expressed as CuO), 0-50 wt.% magnesium, chromium, zinc, barium and/or calcium oxide (expressed as MgO, Cr2O3, ZnO, BaO and CaO) and less than 20 wt.% nickel oxide (expressed as NiO) with respect to CuO.

    Abstract: Polymers and oligomers of formula (I), based on unsatd. 2-10C hydrocarbons and with one or two 2-oxazolinyl terminal gps., in which A = polymer or oligomer residue derived from the unsatd. hydrocarbon (A'), and R = H, 1-10C alkyl, 6-10C aryl or 3-6C cycloalkyl. Also claimed are (i) comb polymers (II) obtd. by cationic ring-opening homo- or co-polymerisation of (I); (ii) comb polymers (III) obtd. by reacting (I) with base polymers contg. reactive gps.; (iii) thermoplastic moulding materials or thermosets contg. (I), (II) or (III) or mixts. thereof; (iv) a process for the prodn. of (I) by polymerisation or oligomerisation of (A'), modification with one or two terminal ester gps., and Lewis acid-catalysed ring closure with 2-amino-1- alcohols; (v) processes for the prodn. of (II) and (III) under the above conditions; (vi) films, fibres and mouldings obtd. from the materials claimed in (iii).
