TERMINAL POLYVINYL FUNCTIONAL MACROMERS, POLYMERS THEREOF AND CONTACT LENSES MADE THEREFROM

摘要

Terminal polyvinyl functional macromers, polymers thereof and contact lenses made therefrom Disclosed is a poly-unsaturated polysiloxane of the formula I, (I) wherein at least three of A are a reactive vinyl containing group as defined in the specification and the further variables are as defined in the specification. The invention concerns even polymers of those compounds and copolymers thereof with up to 95 % of one or more hydrophilic or hydrophobic reactive vinyl monomers, or mixture thereof. The respective (co)polymers are suitable for the manufacture of contact lenses.
