    摘要: 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.

    摘要: The present invention relates to a new organic heterocyclic isocyanate which is the reaction product of an organic diisocyanate and an amino or hydroxy nitrile. The invention also relates to a process of producing such isocyanates by reacting an excess of the diisocyanate with the nitrile under conditions under which the nitrile will not decompose and then maintaining the reaction mixture at an elevated temperature until the isocyanate nitrile adduct cyclizes. The reaction may be carried out in the presence of a catalyst for isocyanate addition reactions. Additionally, the invention relates to a process for the production of polyurethane by the reaction of the heterocyclic isocyanates with compounds carrying at least two isocyanate reactive hydrogen atoms per molecule.
