Contact lens material

   
   

A method for reducing the modulus of polymer silicone 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.

Um método para reduzir o modulus de composições do hydrogel do silicone do polímero empregando polysiloxanes monomeric endcapped com trimethylsilyl para reduzir a densidade crosslinking do hydrogel. A síntese consiste único em uma polimerização catalyzed da abertura do anel da embarcação ácido e pode ser empregada para produzir os copolymers úteis como materiais da lente de contato do hydrogel.
