Abstract

Process for obtaining resins for heat-resistant laminates characterized in that it consists of reacting a thermostable liquid phenolic resin, prepared by the partial reaction of a phenol chosen from those of the class consisting of phenol, monophenols substituted by alkyl and aryl radicals, unsubstituted diphenols, and mixtures thereof, with an excess of an aldehyde selected from the group consisting of saturated aldehydes and mixtures thereof in the presence of a catalyst from the group consisting of calcium and barium hydroxides, neutralization with carbon dioxide to form carbonate with the cation of the catalyst, and the separation of the carbonate; with 20 to 80% by weight of the composition, of a phenyl-methylene ether corresponding to the general formula. ** (See formula) ** wherein "R" represents a member of the class consisting of ethylenically unsaturated aliphatic radicals containing 3 or 4 carbon atoms, and halogenated derivatives of said unsaturated aliphatic radicals.
