Description
Summary:New ethoxy-functional metallosiloxanes with a high activity in alkoxysilane polycondensation reactions have been synthesized with the use of Rebrov salts. A possibility of using the obtained methyldiethoxysiloxy derivatives of metallosiloxanes as binders for the preparation of homogeneous polydimethylsiloxane-containing compositions by realizing the concept of “liquid filling” has been demonstrated. The properties of the resulting compositions have been studied. [Display omitted] •New ethoxy-functional metallosiloxanes were synthesized with the use of Rebrov salts.•Obtained metallosiloxanes have a high activity in the alkoxysilane polycondensation reactions.•Use of metallosiloxanes as binders for the preparation of homogeneous PDMS-containing compositions has been demonstrated.•The resulting compositions exhibited good mechanical characteristics, high thermal stability and solvent resistance.
