Ionic silicone hydrogel polymers displaying improved thermal stability. More specifically, the present application relates to a polymer formed from reactive components comprising at least one silicone component and at least one ionic component comprising at least one anionic groupmore specifically methacrylic acid (MAA). The polymers of the present invention display good thermal stability and desirable protein uptake.
L'invention concerne des polymères d'hydrogels de silicone ioniques présentant une meilleure stabilité thermique. Plus spécifiquement, la présente invention concerne un polymère composé de constituants réactifs comprenant au moins un constituant siliconé et au moins un constituant ionique comprenant au moins un groupe anionique, plus particulièrement de l'acide méthacrylique (MAA). Les polymères de la présente invention présentent une bonne stabilité thermique et une fixation de protéines souhaitable.
