Title:
MDQ PHENYL VINYL SILICONE RESIN AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2016/082287
Kind Code:
A1
Abstract:
The present invention relates to MDQ phenyl vinyl silicone resin. The MDQ phenyl vinyl silicone resin has a structure represented by the following general formula: (Ph2SiO)a(ViMe2SiO0.5)b(Me3SiO0.5)c(SiO2)d, wherein Ph is phenyl, Me is methyl and Vi is vinyl; the value of a ranges from 0.1 to 1; the value of b+c ranges from 0 to 0.1, and b>0; the value of d ranges from 0 to 0.8, and a+b+c+d>0; the value of a/d ranges from 1.6 to 2.5; and the value of (b+c)/d ranges from 1.6 to 2.5. The present invention also provides a method for preparing the MDQ phenyl vinyl silicone resin. According to the method, the viscosity, the refractive index and the vinyl content of a product are controlled through conditions such as the monomer raw material ratio, the reaction time, the temperature and the pH value, the manufacturing conditions are mild, simple and feasible, the raw material source is wide, and the repeatability is good.
