Title (EN) PROCESS FOR MAKING CATIONIC HYDROPHILIC SILOXANYL MONOMERS
(FR) PROCEDE DE FABRICATION DE MONOMERES DE SILOXANYLE HYDROPHILES CATIONIQUES
Abstract:
(EN) The present invention relates to polymeric compositions useful in the manufacture of biocompatible medical devices. More particularly, the present invention relates to certain cationic monomers capable of polymerization to form polymeric compositions having desirable physical characteristics useful in the manufacture of ophthalmic devices. Such properties include the ability to extract the polymerized medical devices with water. This avoids the use of organic solvents as is typical in the art. The polymeric compositions comprise polymerized cationic hydrophilic siloxanyl monomers prepared by the process disclosed herein.
(FR) L'invention concerne des compositions polymères utiles dans la fabrication de dispositifs médicaux biocompatibles. Plus particulièrement, elle concerne certains monomères cationiques polymérisables en vue de former des compositions polymères possédant des caractéristiques physiques souhaitables utiles dans la fabrication de dispositifs ophtalmiques. Ces propriétés comprennent la capacité à extraire les dispositifs médicaux polymérisés avec de l'eau. Ceci empêche l'utilisation de solvants organiques comme c'est le cas dans l'art antérieur. Les compositions polymères contiennent des monomères de siloxanyle hydrophiles cationiques polymérisés préparés par le biais du procédé de l'invention.
