Abstract

A novel approach, with high selectivity, to obtain novel polysiloxanes containing sulfone groups from sulfur-bridged cyclosiloxane monomers was carried out without the use of catalysts; instead, sulfur oxidation was performed. The sulfide oxidation reaction can induce ring-opening polymerization of the cyclosiloxanes through cleavage and rearrangement of Si–O–Si bonds. Our findings present novel insights to synthesize new polysiloxanes.
