A method of producing a compound represented by the following general formula (3):
[wherein R is a bivalent aliphatic group having a carbon number of 1-16 or a bivalent aromatic group], which comprises a step (i) of reacting a compound represented by the following general formula (1):
with a carboxylic acid halide represented by the following general formula (2):
[wherein R is a bivalent aliphatic group having a carbon number of 1-16 or a bivalent aromatic group and X is a halogen atom] in the presence of a basic compound to form an ester, and a step (ii) of conducting a heat treatment after the step (i) to decompose an oligomer in the ester.
Curable compositions are disclosed which contain (I) an advanced resin composition prepared by reacting epoxy resins with active hydrogen-containing compounds which contain mesogenic moieties and (II) a suitable curing agent.

Thermosettable vinyl ester resin compositions are prepared from polyepoxide compounds, optionally, monoepoxide compounds, at least one of which contains a mesogenic or rigid rodlike moiety and a monounsaturated monocarboxylic acid. These vinyl ester resins can be mixed with polymerizable ethylenically unsaturated monomers which can, if desired, contain a mesogenic or rigid rodlike moiety.
