Latest Patents
W James Hammer holds a patent for a hydroxy-substituted polymeric shaped hydrogel article. This patent describes a process for preparing ophthalmic devices through thermoforming a polymer derived from ethylenically-unsaturated monomers. The process involves heating the polymer in a mold or in sheet form at temperatures ranging from 100°C to 400°C for a duration of 5 seconds to 15 minutes. After cooling, the polymer is solvolyzed to create a hydroxy-substituted polymeric shaped article, which can be further hydrated to produce a shaped hydrogel article. Notably, when the polymer is derived from vinyl trihaloacetate, it exhibits a syndiotactic stereochemical configuration. This innovative approach has the potential to enhance the functionality of ophthalmic devices.
