A method for producing a high molecular weight polyester having swell of 1-200 percent is described. In the method, a mixture consisting of (a) 100 parts by weight of a linear saturated polyester; (b) 0.3&tilde;10 parts by weight of a mixture, as a coupling agent, which is composed of (1) 0-100 percent by weight of a bifunctional epoxide ingredient containing 2 epoxide groups per molecule and (2) 100-0 percent by weight of a polyfunctional epoxide ingredient containing 3 and more epoxide groups per molecule; and (c) 0.01&tilde;5 parts by weight of metal salt of carboxylic acid as a catalyst for coupling reaction, is heated at a temperature higher than a melting point of said polyester resin.

A process for producing a curable resin comprises reacting (a) at least one cyanate ester compound selected from the group consisting of polyfunctional cyanate esters having 2 or more cyanato groups per one molecule, prepolymers of the cyanate esters or mixtures thereof with (b) at least one compound having 1,2-epoxy group(s) and radical-polymerizable unsaturated double bond(s) in its molecule, the cyanate ester compound (a) and the compound (b) being used so that the ratio of the cyanato group to the 1,2-epoxy group is in the range of about 1:0.25 to about 1:2, in the presence of (c) a radical polymerization inhibitor at a temperature of about 90.degree.--about 140.degree. C. The curable resin produced according to the present invention is capable of giving cured products having excellent heat resistance and electrical properties.
