ABSTRACT:
Adducts containing terminating nitro (nitroso) groups and one or more mesogenic moleties are prepared by reacting (A) at least one compound containing an average of more than one vicinal epoxide group per molecule with (B) at least one compound containing one or more nitro (nitroso) groups and an average of one reactive hydrogen atom per molecule; with the proviso that at least one member of components (A) and (B) contains a mesogenic moiety. Reaction of part or all of the aliphatic hydroxyl backbone groups by etherification, conversion to a halide, urethanation, oxidation to a ketone, or reduction of said ketone to an alkane, decreases the amount of hydroxyl group functionality. Reduction of these adducts provides amines which are useful as curing agents for epoxy resins.
