ABSTRACT:
Hydrophilic modifier monomers of the formula [X-T].sub.z 'G are disclosed wherein X is a reactive group, G is a hydrophilic group and T is a divalent linking group, z' being a number up to the available valence of G, excess G 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.
