Abstract

PURPOSE: The titled composition, containing a polyfunctional epoxy compound, a condensation product of phenol with an aldehyde and a polysulfide polymer, and capable of giving a cured resin having improved heat resistance and flexibility.
CONSTITUTION: A composition obtained by incorporating (A) a polyfunctional epoxy compound, e.g. diglycidyl ether of bisphenol A, with (B) a condensation product of phenol with an aldehyde, e.g. novolak resin synthesized from phenol, etc. and formaldehyde by the acidic catalytic reaction, and (C) a polysulfide polymer, e.g. the formula, which is a polymer, containing sulfide bonds and terminal thiol groups and preferably a very small amount of branched units in the molecule and has molecular weight of about 500W10,000, at a weight ratio of (A)/(B)/(C) of 1:(0.05W2):(0.05W0.7), preferably 1:(0.2W0.7):(0.1W0.5), and kneading the resultant mixture with a catalyst, e.g. triethanolamine, at a weight ratio to the component (A) of (0.01W20):100 under heating at about 70W80°C. The resultant composition is then cured at about 150W200°C.
