Introduction

Stephen Ross Clarke is an accomplished inventor based in Morphett Vale, Australia. He has made significant contributions to the field of polymer chemistry, particularly in the development of novel polysiloxane copolymers. With a total of two patents to his name, Clarke's work has implications for various industrial applications.

Latest Patents

Clarke's latest patents include a process for manufacturing high molecular weight, alternating polysiloxane copolymers through solid-liquid phase interfacial polymerization. This innovative method allows for the creation of copolymers consisting of alternating siloxane repeating units, such as diphenylsiloxane and dimethylsiloxane. The process is efficient, operating smoothly at room temperature, and does not generate cyclic siloxane species, making it a non-reversible reaction. The resulting polysiloxanes can be utilized as thermoplastic elastomers, suitable for applications such as sealants, fillers, and films.

Another notable patent involves the method of making dialkali metal silanolates and siloxanolates. This process utilizes a heterogeneous interfacial reaction to manufacture dialkali metal organosilanolate and siloxanolate salts from cyclic siloxanes or linear silicone polymers. The resulting salts serve as monomers for various polymerization processes and can also act as ring-opening initiators for the base-catalyzed polymerization of cyclic siloxanes.
