With the widening of the application fields of phenolic resins, many types of modifiers have been used to modify the molecular structure of phenolic resins. In recent years, more and more researchers have focused on the discussion of the properties of modified phenolic resins and gradually ignored the research on the synthesis processes that can affect the molecular structure and properties of phenolic resins. This review covers the synthesis processes used to prepare chemically modified phenolic resins and classifies and summarizes them. The types of modifiers, the timing in adding modifiers, and the advantages and disadvantages of different synthesis processes are considered. A possible synthesis process strategy for the preparation of different modified phenolic resins is provided, and this has a certain guiding significance for the research on high-performance phenolic resins.

随着酚醛树脂的应用领域的扩大，已使用多种类型的改性剂来改性酚醛树脂的分子结构。近年来，越来越多的研究人员开始关注改性酚醛树脂的性能讨论，而逐渐忽略了可能影响酚醛树脂分子结构和性能的合成方法的研究。这篇综述涵盖了用于制备化学改性酚醛树脂的合成方法，并对它们进行了分类和总结。考虑了改性剂的类型，添加改性剂的时间以及不同合成方法的优缺点。提供了一种可能的合成方法，用于制备不同的改性酚醛树脂，
