An adduct is prepared by reacting (A) a compound containing at least one epoxy group per molecule, with (B) a compound containing at least one epoxide reactive group per molecule selected from the group consisting of phenolic, thiol, secondary amine and carboxyl; wherein (i) when compound (A) is a polyepoxide, compound (B) contains a single epoxide reactive group per molecule; (ii) when compound (A) is a monoepoxide it is a monoglycidyl ether and compound (B) contains at least two epoxide reactive groups per molecule; and (iii) at least one of components (A) and (B) contains a rodlike mesogenic moiety. These adducts are useful in the preparation of polyurethanes.
