ABSTRACT:
Monomeric polyparaffinsiloxanes end-capped with activated unsaturated groups and polymers and copolymers thereof are disclosed herein for use as contact lenses and biomedical devices with improved properties, such as, oxygen transportability, hydrolytic stability, biological inertness, transparency and improved strength without the use of fillers. The polymer composition comprises a poly(organoparaffinsiloxane) monomer .alpha.,.omega. terminally bonded through divalent hydrocarbon groups to polymerized free radical polymerizably activated unsaturated groups.
