Abstract

See full text

The invention provides a class of amphiphilic branched macromers and the uses thereof. An amphiphilic branched polydiorganosiloxane macromer of the invention is produced from an α,ω-dimethacryloyl-terminated polydiorganosiloxane vinylic crosslinker comprising one or more ATRP-containing siloxane units having one substituent having an ATRP initiator by ATRP polymerization of one or more hydrophilic vinylic monomers. It comprises at least two polydiorganosiloxane polymer chains each having at most two terminal methacryloxy groups, dangling hydrophilic polymer chains each having a polymerizable or non-polymerizable terminal group, and one or more hydrophilic polymer chains as linkages between two polydiorganosiloxane chains. The present invention is also related to a silicone hydrogel contact lens, which comprises units derived from a polydiorganosiloxane-containing amphiphilic branched macromer of the invention.
