| Abstract: | A new type of phenolic resin was synthesized by using organophosphonic acid as catalyst, and the catalyst was circulated through the sysnthesis. The synthesized phenolic resin was determined and characterized by means of infra-red spectrometer and gel chromatography. The results showed the synthesized phenolic resin had high yield, less unreacted phenol and narrow molecular weight distribution. The circulating use of the catalyst lowered the cost of the systhesis and was of environmental protection. |
