    • Provided is a method of producing a low viscosity phenol-modified aromatic hydrocarbon formaldehyde resin (C), including subjecting an aromatic hydrocarbon formaldehyde resin (A) and a phenol (B) to condensation reaction under the presence of an acid catalyst. The method includes: terminating, when a reaction mixture has a viscosity at 25° C. of 200 to 1,500 mPa·S, the condensation reaction by adding an inorganic basic compound and/or a tertiary amine compound having a boiling point of 300° C. or more; and distilling and removing the phenol (B) unreacted and a low boiling component after termination of the condensation reaction, whereby there can be produced a low viscosity phenol-modified aromatic hydrocarbon formaldehyde resin which is kept in a liquid state and contains small amounts of unreacted phenols, and in which increase in viscosity is small even after removal of low boiling components.
    • 本发明提供一种低粘度苯酚改性芳香族甲醛树脂(C)的制造方法,其特征在于,在酸催化剂的存在下,使芳香族甲醛树脂(A)和苯酚(B)进行缩合反应。 该方法包括:当反应混合物在25℃下的粘度为200至1,500mPa.S时,终止通过加入沸点为300℃的无机碱性化合物和/或叔胺化合物的缩合反应 。 或者更多; 并在缩合反应结束后蒸馏除去未反应的苯酚(B)和低沸点成分,由此可以制备保持液态的低粘度苯酚改性芳香族甲醛树脂,并含有少量未反应的 即使在除去低沸点组分之后,粘度的增加也很小。
