Shaped biomedical articles made of polysiloxane polymers.

摘要

There are disclosed novel polysiloxane copolymers prepared by the copolymerization of polysiloxane monomers containing hydrophilic sidechains with polymerizable comonomers to form polymers in a cross-linked network. The resulting polymers may be used to form shaped biomedical articles and in particular there are disclosed contact lenses which are water-absorbing, soft, flexible, hydrolytically stable, biologically inert and hydrophilic.
