Abstract
The invention provides a hydrophilized carbosiloxane vinylic monomer which comprises (1) a poly(carbosiloxane) segment, (2) one sole ethylenically unsaturated group, and (3) at least one terminal or pendant group which is a hydrophilic group or hydrophilic polymer chain. The present invention is also related to a polymer, an actinically-crosslinkable silicone-containing prepolymer, a silicone hydrogel polymeric material, or a silicone hydrogel contact lens, which comprises monomeric units derived from a hydrophilized carbosiloxane vinylic monomer of the invention.
