The Polyetherification Modified Reaction on Silicone Oil

Nowadays, polyether silicone oil is widely used in many aspects of chemical industry. In this paper, the synthesis of polyether modified polysiloxane was studied and its technology was the best choice. This paper discussed the synthesis of polyether modified polysiloxane materials during the synthesis ratio, catalyst amount, reaction time and temperature on the synthesis of polyether polysiloxane low conversion rate of hydrogen silicone oil. The results showed that synthesis of polyether modified polysiloxane of the best technology: the C=C of allyl alcohol and the Si-H in low-hydrogen silicone polyether feed ratio was 1:1.2, the catalyst material is 33 μg / g, the reaction temperature is 110 °C, reaction time to 8 h.
