摘要：
An epoxy resin composition comprising a polyglycidyl ether prepared by reacting a 3-methyl-6-alkylphenol in the presence or absence of a phenol other than the 3-methyl-6-alkylphenol with an aldehyde to obtain a novolak, and then reacting the novolak with an epihalohydrin, which composition is useful in electronic fields, for example, for encapsulating semiconductor products or for the production of printed circuit boards.
