CA 1337938

Hydrophilic modifier monomers of the formula (X-div)z Hy are disclosed wherein X is a reactive group, Hy is a hydrophilic group and div is a divalent linking group, z being a number up to the available valence of Hy, excess Hy valences being taken up by hydrogen. The monomers of the invention can be used to boost the hydrophilic nature of a wide variety of polymeric materials or be polymerized themselves with varying degrees of copolymerizable monomers. They are particularly suited for making hydrophilic contact lens materials.
