| Abstract: | The polysiloxanes with specified content of vinyl groups was prepared in anhydrous tetrahydrofuran （THF） by anionic ring-opening polymerization of 1,3,5-trimethyl-1,3,5-trivinylcyclotrisiloxane and hexamethylcylotrisioxane. In the presence of n-butyllithium, the polysiloxanes with specified content of silicon hydrogen bonds was prepared in anhydrous THF by cationic ring-opening polymerization of 1,3,5,7-tetramethylcycllotetrasiloxane and hexamethylcylotrisioxane in the presence of concentrated sulfuric acid. The results provide a fundamental for the national defense reference materials of polysiloxanes. |
