    • The present invention provides a phenol resin having, as a unit in its main-chain skeleton, a structure represented by the following general formula (I), as well as a resin composition using the same. According to the phenol resin of the invention, epoxylation thereof, chemical modification thereof, reaction thereof with an epoxy resin, and the like are facilitated. Phenol resins ranging from low-molecular-weight resins rich in fluidity to high-melting resins can be synthesized, and these phenol resins are industrially useful. When the phenol resin of the present invention is used as a hardening agent for epoxy resin etc., its resin composition can give a cured product of high Tg without deteriorating adhesiveness.
    • 本发明提供一种在其主链骨架中作为单元具有由以下通式(I)表示的结构的酚醛树脂以及使用其的树脂组合物。 根据本发明的酚醛树脂,其环氧化,化学改性,与环氧树脂的反应等有利。 可以合成苯酚树脂,从低流动性的低分子量树脂到高熔点树脂,这些酚醛树脂在工业上是有用的。 当本发明的酚醛树脂用作环氧树脂等的硬化剂时,其树脂组合物可以得到Tg高的固化产物,而不会降低粘附性。
