| Abstract: | In this study,polyether-modified siloxane was synthesized by hydrosilation of polyhydrosiloxane and allyl-polyether(APE),using catalyst and toluene as solvent.The optimum reaction conditions were also obtained:the molecular weight of APE is 1 000,the molar ratio of Si-H band to APE is 1 ∶1.2,reaction temperature is 90 ℃,amount of catalyst is 30×10-6,and the concentration of solvent is 25%.The polyether modified siloxane is transparent,and has superior performance.It can be used at a wider ranges. |
