    摘要： A phenolic resin composition comprises a mixture of 100 parts by weight of a phenol aralkyl resin and 5 to 60 parts by weight of a novolak type phenolic resin having a content of binuclear components of not more than 10% by area, and a content of trinuclear components of not less than 50% by area and a sum content of tri- and tetra-nuclear components of 75% by area based on the total novolak phenolic resin except for the binuclear components, and an epoxy-cured product obtained by curing an epoxy resin while using the phenolic resin composition as set forth in claim 1 as a curing agent. The phenolic resin composition has a low viscosity and, when it is used as a curing agent for epoxy resins, the resulting epoxy-cured product has a low water absorption rate, is excellent in resistance to moisture and has a high glass transition temperature as compared with the cured product obtained using a novolak type phenolic resin as a curing agent.

    摘要： An aromatic polyester amide is produced by reacting hydroxyphenyl-aminophenyl-propane with aromatic dicarboxylic acid dihalide in the presence of an inert organic solvent, and bringing the organic solvent phase containing the mixture of the reaction products of the above reaction into contact with an aqueous phase containing an acid-acceptor, whereby completing polycondensation reaction. In order to control the dissolution of water into the organic solvent phase while maintaining an adequate level of miscibility between the organic solvent phase and the aqueous phase, a neutral salt of inorganic electrolyte, such as sodium chloride, is added to the aqueous phase containing the acid-acceptor.
