| Abstract: | A novel MQ silicon resin(1) was synthesized by hydrolysis condensation reaction under acidic conditions from tetraethoxysilane,hexamethyl-disiloxane and divinyltetramethyldisiloxane.The structure was characterized by 1H NMR,FT-IR,and XRD.The wettibility and thermal stability of 1 were investigated by static contact angle and thermogravimetric analysis,respectively.The results showed that the water contact angle of 1was 139° and 5% weight loss temperature was 456 ℃.1 exhibited hydrophobic property and high thermal stability. |
