| Abstract: | Vinyl-substituted MQ silicone resins were prepared by the cohydrolysis of 1,3-divinyl-1,1,3,3- tetramethyl disiloxane and tetraethyl orthosilicate. The influence factors to the yields of the MQ silicone resin were also studied. The results showed that the preferable process was： the dosage of catalyst, hydrochloric acid with concentration of 35-38 % was 1.1%（volume ratio）. The dosage of de-ionized water and ethanol were 11% and 22 %（volume ratio）, respectively. The reaction time was 1h and the reaction temperature was between 75 and 80℃. |
