    摘要: Polyamines based on derivatives of 1,3-bissubstituted 2-propanol containing a multiplicity of amino groups, the latter containing at least one primary amino group and additionally further N-basic groupings, prepared by reacting 1,2,3-trisubstituted propane compounds with bis(primary amines or with monoamines and bis(primary amines).The polyamines according to the invention are clear to yellowish or yellow products which, at room temperature, form viscous to highly viscous liquids or may be paste-like or wax-like. They may be used, inter alia, advantageously as starting products for the preparation of thermosetting, in particular water-dispersible and cataphoretically depositable binders based on aminourethanes for coating solid substrates, in particular metals.
