Abstract:
The present invention relates to a fast curing compositions comprising a (meth)acrylamide functionalized hydrophilic silicone monomers having a polyether moiety containing a branched linking group. In one embodiment, such compositions are useful for preparing water-absorbing silicone-hydrogel films for contact lens applications. In one embodiment, the (meth)acrylamide monomers disclosed here have a branched linking group on the polyether moiety which makes it possible to produce hydrophilic polyether modified silicone copolymers without the need to separate various by-products including, but not limited to, unreacted, isomerized polyether and associated high molecular weight by-products.
