摘要
本文报导了在高温下使苯酚与甲醛缩合，未经浓缩而得到粘度较大的酚醛树脂的方法。
the method for synthesis of resols was reported in this paper.In high temperature,phenol and formaldehyde were condensed to form resols with higher viscosity without concentration.The effects of temperature and time of condensation on viscosity of the product were carefully examincd.
