摘要
采用优化工艺聚合得到的PF树脂的固含量为51．1％，数均分子量（m^—n）和重均分子量为（m^—n）分别为267和331，分子量主要分布在200—400之间，分散指数为1．24，表面张力较小且变化平缓，具有较好的渗透性能，同时，游离酚和游离醛的含量低。
The phenol formaldehyde resin was synthesized by the optimization craft, solid content is 51.1%, number average molecular weight and weight average molecular weight are 267 and 331, molecular weight during 200 to 400 and the dispersible index is 1.24. The surface tension is lower and the changes is gently, and having hatter impregnation. Free phenol and free formaldehyde become lower.
