    摘要: 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.

    摘要: The invention is related to a class of hydrophilic polymers each comprising one sole thiol-containing terminal group. The hydrophilic polymers are highly reactive towards azetidinium groups of an azetidinium-containing polymer upon heating and can find particular use in for producing water-soluble highly-branched hydrophilic polymeric material useful for producing water gradient contact lenses.

    摘要: The invention is related to a class of hydrophilic poly(meth)acrylamide-based copolymer comprising dangling (i.e., pendant) phosphorylcholine groups and dangling (i.e., pendant) reactive groups or chains each of which comprises one carboxyl group, one thiol group, or one primary or secondary amino group. The hydrophilic copolymers have a relatively high affinity to a base coating of a polyanionic polymer on a medical device or contact lens and are reactive towards azetidinium groups of an azetidinium-containing polymer upon heating. They can find particular use in producing water-soluble highly- branched hydrophilic polymeric material and in producing water gradient contact lenses.

    摘要: Described herein are dimethyl acetal-containing UV-absorbing compounds and their uses in preparing UV-absorbing polyvinyl alcohol prepolymers suitable for producing UV- absorbing contact lenses capable of blocking ultra-violet ("UV") radiation and optionally (but preferably) violet radiation with wavelengths from 380 nm to 440 nm, thereby protecting eyes to some extent from damages caused by UV radiation and potentially from violet radiation. This invention also provides a UV-absorbing polyvinyl alcohol prepolymer.
