Abstract: 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%.

Abstract: Products of glycidyl ether of a mono or polyhydric phenol as well as methods to manufacture the same. In some instances, the product of glycidyl ether of a mono or polyhydric phenol has an epoxy equivalent weight (“EEW”) and a hydroxyl value (“HV”), wherein the epoxy equivalent weight multiplied by the hydroxyl value (EEWxHV) is a value from 1 to 10. A process for producing the product of glycidyl ether of a mono or polyhydric phenol typically includes reacting an epihalohydrin with a mono or polyhydric phenol in the presence of a catalyst to produce a halohydrin ether; and dehalogenating the halohydrin ether to form the product of glycidyl ether of a mono or polyhydric phenol.
