摘要： A phenolic novolak resin comprising a compound represented by the general formula [I]: ##STR1## wherein X is H or ##STR2## R is an alkyl group having 1 to 4 carbon atoms, and n is 1 to 10, particularly a phenolic novolak epoxy resin, and material, and a cured substance therefrom, and a process for producing the resin are disclosed. This resin is excellent in heat resistance and in reluctance to absorb water as compared with conventional phenolic resins, and useful in sealing electronic parts, molding, and laminating.

摘要： This invention relates to a method for stabilizing unsaturated cycloacetal resin produced by reacting (I) cycloacetal compound prepared by the condensation of polyhydric alcohol more than tri-hydric and unsaturated aldehyde, with (II) unsaturated alcohol having a radical-polymerizable unsaturated bond and an alcoholic hydroxyl group in the same molecule, and optionally further with one or more compounds selected from the group consisting of polyhydric alcohol, hydroxy polyether and hydroxy polyester, in the presence of acid catalyst, characterized by adding one or more compounds selected from the group consisting of ammonia, primary amine, secondary amine, tertiary amine, quaternary ammonium salt, hydrazine and its derivatives in an amount of 0.01 to 5 parts by weight per 100 parts by weight of the produced unsaturated cycloacetal resin during the reaction of producing the unsaturated cycloacetal resin and/or after the reaction and maintaining pH of the unsaturated cycloacetal resin (pH of a 50% methyl alcohol solution of the resin) at more than 4.
