    摘要: A novel, substantially linear aromatic polyester comprising 6,6'-(ethylenedioxy)di-2-naphthoic acid as a main acid component and an aliphatic glycol having 2 to 10 carbon atoms in the main chain of the glycol as a main glycol component. The aromatic polyester is prepared by condensing an ethylene glycol diester of 6,6'-(ethylenedioxy)di-2-naphthoic acid, or a mixture of a major proportion of said naphthoate with a dicarboxylic acid, a diol, a hydroxycarboxylic acid or an ester-forming derivative thereof, at an elevated temperature. The aromatic polyester has excellent mechanical properties such as strength and Young's modulus.

    摘要: A process for producing a thermoset resin, which comprises reacting (A) a poly(cyclic iminoether), (B) an ethylenically unsaturated compound having a functional group reactive with the poly(cyclic iminoether), and (C) an ethylenically unsaturated monomer having no functional group reactive with the poly(cyclic iminoether), in the presence of an acid catalyst and a radical catalyst. Instead of the compound (B), there may be used the compound (D), i.e. a compound having at least two equivalents of at least one group selected from the class consisting of carboxyl, hydroxyl, amino, epoxy and carboxylic anhydride groups in the molecule and being free from an ethylenically unsaturated bond. The present application provides also a thermosetting composition and a thermoset resin.
