【Abstract】 Polyether amino silicone modified polysiloxane was hydrophilic silicone surfactant.It was mostly applied in the field of pesticide industry,textile industry,daily chemical etc.In this paper,the unsaturated epoxy-containing polyether was synthesized by unsaturated polyether macromolecules and 1-chloro-2,3-epoxy propane.It was then reacted with low hydrogen containing silicone oil via hydrosilylation to produce epoxy-containing polyether silicone.In the end,diethylamine was used to open the epoxy bond to get the final product.The effects of the mass ratio,the reaction temperature and the reaction time on the conversion of hydrogen-containing silicone oil were studied.And the best values were obtained.The structure of the key intermediate and the product was characterized by IR.And its surface activity was determined.更多还原
