    • 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.

    • A preparation process of phenol aralkyl resin from phenol compound and aralkyl compound by controlling the temperature of reaction mass in the range of 70 to 240.degree. C. and simultaneously controlling the temperature of vapor phase potion and vapor-liquid interface portion of manufacturing equipment so as to keep the wall surface of the vapor phase portion and vapor-liquid interface portion in a wet state. The invention can prevent scale adhesion to the interior of manufacturing equipment, remarkably reduce the number of washing and scale removing procedures on the manufacturing equipment, and enable efficient manufacture of phenol aralkyl resin. When the phenol aralkyl resin obtained is used for a molding material, molded articles having excellent heat resistance and high reliability can be provided.
    • 通过将反应物质的温度控制在70〜240℃的范围内,由苯酚化合物和芳烷基化合物制备苯酚芳烷基树脂,同时控制制造设备的气相药液和气 - 液界面部分的温度,以便 以保持气相部分和汽液界面部分的壁表面处于湿润状态。 本发明能够防止水垢附着在制造装置的内部,显着地减少了制造装置的洗涤和除垢程序,能够高效地制造苯酚芳烷基树脂。 得到的苯酚芳烷基树脂用于成型材料时,可以提供耐热性优异,可靠性高的成型品。
