    摘要: The present invention relates to bis-oxazolidines corresponding to formula (II) ##STR1## wherein R represents a branched, saturated, aliphatic hydrocarbon radical containing 5 to 8 carbon atoms.The present invention also relates to oxazolidine mixtures, which are also suitable as hardeners for plastics precursors containing isocyanate groups, consisting essentially ofa) bis-oxazolidines corresponding to formula (II) above andb) 0.03 to 0.3 moles per mole of component (a), of compounds corresponding to formula (III) ##STR2## wherein R represents a saturated, branched, aliphatic hydrocarbon radical containing 5 to 8 carbon atoms.The present invention additionally relates to a process for the production of these oxazolidine mixtures and to their use in combination with polymer precursors containing isocyanate groups for coating or sealing compositions.
