Abstract (en)
[origin: WO2020032973A1] An ophthalmic device is disclosed that is a polymerization product of a monomeric mixture comprising: (a) a major amount of one or more non-silicone- containing hydrophilic monomers; (b) a crosslinking agent mixture comprising (i) one or more first crosslinking agents containing at least two ethylenically unsaturated reactive end groups, wherein the at least two ethylenically unsaturated reactive end groups are (meth)acrylate-containing reactive end groups and (ii) one or more second crosslinking agents containing at least two ethylenically unsaturated reactive end groups wherein at least one of the ethylenically unsaturated reactive end groups is a non-(meth)acrylate reactive end group, and (c) one or more hydrophilic polymers or copolymers comprising one or more hydrophilic units and a thio carbonyl thio fragment of a reversible addition fragmentation chain transfer ("RAFT") agent wherein the ophthalmic device has an equilibrium water content of at least about 45 weight percent.
