Abstract (en)
[origin: WO0105578A1] A melt processable hydrogel block copolymer is made from hydrophilic and hydrophobic monomers and has sufficient internal association without crosslinking to provide a dimensionally stable hydrogel at temperatures up to at least about 60 DEG C. The polymer may be thermally processed into an ophthalmic device, and then hydrated into a hydrogel material. Optionally, the polymer may undergo treatment before, during or after hydration to form crosslinks.
