    摘要： The present invention relates to compositions comprising at least one stable, near-monodisperse, non-reactive hydrophilic polymer comprising in said polymer's backbone, a hydrophilic segment having a degree of polymerization of about 10 to about 1000, and a linear silicone segment at at least one terminal end of said non-reactive hydrophilic polymer, wherein said silicone segment comprises between about 6 and about 200 siloxy units, and said non-reactive hydrophilic polymer is associated, via the linear silicone block with a silicone hydrogel. The non-reactive hydrophilic polymers may be incorporated into the formulation from which the silicone hydrogel is made or may be contacted with the silicone hydrogel post formation.
