Oriented compositions derived from nitro group terminated mesogenic epoxy resin adducts

The product resulting from curing a curable composition comprising (1) at least one compound having an average of more than one vicinal epoxide group per molecule;

• and (2) a curing quantity of at least one amine group terminated adduct containing one or more mesogenic moieties per molecule, which adduct results from the reaction of (A) one or more compounds containing an average of more than one vicinal epoxide group per molecule and (B) one or more compounds containing one or more nitro or nitroso groups and one hydrogen atom per molecule which is reactive with an epoxide group thereby forming an adduct essentially free of epoxy groups and containing nitro or nitroso groups followed by (C) reaction of a part or all of the backbone aliphatic hydroxyl groups contained therein, wherein said reactionis an etherification of the hydroxyl group, an esterification of the hydroxyl group, conversion of the hydroxyl group to a halogen, a urethanation of the hydroxyl group or an oxidation of the hydroxyl group to the ketone carbonyl group which is optionally reduced to provide the alkane, and (D) reduction of the nitro or nitroso groups contained therein to amine groups;
• with the proviso that at least one or more mesogenic moieties per molecule are present in either component (A) or (B) or in both (A) and (B);
• wherein said composition is subjected to orientation during curing wherein components (A) and (B) are employed in amounts which provide a ratio of equivalents of hydrogen reactive with an epoxide group, excluding secondary hydroxyl groups formed by epoxide ring opening reaction to form the adduct, per equivalent of epoxide reacted of from about 1:1 to about 100:1.
