Abstract: |
In this study,hyperbranched silicone oil was prepared by Piers-Rubinsztajn reaction in one potand using lab-made single hydroxyl terminated dimethyl silicone oil and low hydrogen silicone oil as raw materials. The structure and properties of the hyperbranched silicone oil were analyzed,and its influence on the properties of phenyl silicone rubber with medium phenyl content was studied. The results showed that hyperbranched silicone oil had good thermal stability and its rheological properties were close to Newtonian fluids. Hyperbranched silicone oil had internal plasticizing effect,and could improve the elasticity of phenyl silicone rubber and reduce the dynamic loss. |
