Resol-type modified phenolic resin composition, production method thereof and adhesive

摘要

According to the present invention, a resol-type modified phenolic resin having a structural unit A represented by the following general formula (1) modified with dimethylphenol and a structural unit B represented by the following general formula (2) A resol-type modified phenolic resin composition is provided. (In the formula (1), m is an integer of 1 or more. When m is 1, R is a methylol group. When m is 2 or more, R is independently A hydrogen atom or a methylol group, and at least one R is a methylol group.) (In the formula (2), n is an integer of 1 or more. When n is 1, R is When n is 2 or more, R is independently a hydrogen atom or a methylol group, and at least one R is a methylol group.)
