Trimethylsilyl-Capped Polysiloxane Macromonomers Containing Polar Fluorinated Side-Chains

摘要

A method for reducing the modulus of polymer siloxane hydrogel compositions by employing monomeric polysiloxanes endcapped with trimethylsilyl to reduce the crosslinking density of the hydrogel. The synthesis consists of a single vessel acid catalyzed ring opening polymerization and may be employed to produce copolymers useful as hydrogel contact lens materials.
