摘要：
A water soluble silicone macromer comprising a siloxane backbone having grafted thereto a suitable number of hydrophilic groups to render the macromer water soluble, the macromer comprising a polymerizable functional group grafted to the siloxane backbone. In one aspect, the present invention provides a water soluble silicone macromer having a structure of Formula (1): where M is a hydrophilic group or segment； L is a hydrophilic or hydrophobic linkage； N is a hydrophilic or hydrophobic group or segment. Q is a polymerizable functional group； x is zero or an integer greater than zero； y is zero or an integer greater than zero； v is zero or an integer greater than zero； and z is greater than zero, with the proviso that both y and v are not zero.
