New synthetic and modified silicones polymers and new applications of previously available ones continue to be a promising area of research. Polysilalkylene siloxanes or hybrid/modified silicones are a comparatively new class of polymeric materials combining the chemical properties of silicones and paraffins in a unique way. Hydrosilylation of dienes is an essential reaction to produce diverse organosilicon compounds such as industrially important silicone products. The objective of this project is to synthesize newly modified silicone monomers and then to characterize their physical properties. The synthetic aspect of this research is concerned with the application of using hydrosilylation reaction in the preparation of new dichlorosilane monomers having different alkyl and aryl pendant groups and different backbone repeat structures. The general scheme for the synthesis of the functional monomers is to use various dienes and dimethyl or phenylmethyl chlorosilane as the reactants and using a Karstedt’s catalyst, which provides a convenient synthesis route to produce a mixture of mono and dichloro alkyl/aryl silicone monomers.
