Polimero akrilikoak oftalmologian. Degradazio-prozesuaren analisia

Abstract

The use of polymeric contact lenses has risen worldwide the last years. During the development of these lenses, acrylic based materials have aroused as the most used polymers due to their optical properties. Taking into account the importance of these polymers, in this work we have explained the history and evolution of the contact lenses together with the properties that optical materials must have. Moreover, three commonly used polymers have been chosen, poly(methylmethacrylate), poly(benzylacrylate) and poly(tert-butylacrylate), and their thermal degradation and their kinetic have been studied.
