摘要: A polyhydric phenol resin is provided. The polyhydric phenol resin comprises a polyhydric phenol resin component and a first component. When the polyhydric phenol resin is characterized in a high-performance liquid chromatography (HPLC), the first component is eluted at a retention time ranging from 27.1 minutes to 28.0 minutes, and based on the total area of the chromatographic peaks of the polyhydric phenol resin, the area percentage of the chromatographic peak of the first component at the corresponding retention time in the spectrum ranges from 1.0% to 20%.

摘要: Polyphenolic condensates and epoxidized products prepared from said condensates are prepared by a reaction utilizing multi catalysts to control the weight average molecular weight (Mw) and the number average molecular weight (Mn). Improved color and ultraviolet absorbance are possessed by the condensates described herein.
