| Abstract: | Both bisphenol-A and (3-) chloropropane oxide were synthesized toa condensed polymer-bisphenol-A epoxy resin in the presence of some catalysts. The results of experiments showed that bisphenol-A low-molecular-weight epoxy resin of which oxirane value is 0.5 can be obtained, under the following conditions. The ratio of bisphenol-A to (3-) chloropropane oxide is 0.1, the concentration of sodium hydroxide is 28.57%, the reaction temperature is 65～75℃,the reaction time is 4.5 h, the mole ratio of chlorotrimethyl phenlid to bisphenol-A is 1%. |
