Abstract: A hydrophilic siloxane copolymer of siloxane and hydrophilic organic monomer/s The copolymers can be functionalized to make them capable of undergoing further polymerization by thermal or actinic radiations. The hydrophilicity of these polymers can be varied by varying the siloxane versus organic monomer ratio thereby going from water dispersible to soluble states. The siloxane content can be tuned accordingly in order to provide moderate to high oxygen permeability. These copolymers can be used as a single component curable composition which results in hydrogels to minimize the presence of leachable components thus by reducing the processing cost. The polymers may also find applications in personal care formulations as copolymers, film-formers, hydrogels, coating, emulsions/latex etc.
