| Abstract: | the polyhydroxyether sulfone was synthesized from bisphenol-S and epichlorohydrin in the presence of polyethylene glycol as catalyst.The kinetics of this polymer formation was investigated by taking into account the consumption of the alkali added. The apparent reaction order of phenolic group with epichlorohydrin and end epoxide group in oligomer are all second order.The rate constants and activation energy were determined. |
