摘要

本发明提供一种改性多元羟基树脂、环氧树脂、环氧树脂组成物及其硬化物。本发明涉及一种改性多元羟基树脂，其是使下述通式(1);所表示的多元羟基化合物与包含苯乙烯类或苄基化剂的芳香族改性剂进行反应，将式(a)所表示的源自芳香族改性剂的取代基取代于多元羟基化合物的苯环上而获得的改性多元羟基树脂，且以凝胶渗透色谱法来测定的数量平均分子量Mn为1000以上、5000以下，并且重量平均分子量Mw与数量平均分子量Mn的比Mw/Mn为2以上。;and an aromatic denaturant including styrenes or a benzilization agent and substituting a substituent derivated from the aromatic denaturant, which is represented by formula (a), on benzene rings of the polyhydric hydroxyl compound, and a number average molecular weight Mn evaluated by gel permeation chromatography is 1000 to 5000 and a ratio Mw/Mn of a weight average molecular weight Mw and the number average molecular weight Mn is 2 or more.
