Method for producing hydrophilic siloxanyl monomers cationic

摘要

A forming monomer removable medical device obtainable cationic water by SomeProcedure comprising the steps of: providing a compound containing siloxane hydride, dissolving the compound containing siloxane hydride in a solvent or combination of solvents; treating compound siloxane contains hydride dissolved with an allyl halide and a catalyst conventionally dehidrolización to form a first reaction mixture; heating the first reaction mixture in a nitrogen atmosphere for a time sufficient to darcomo result a quantitative loss of reactants as determined by a technique analíticaapropiada thereby providing a monomer mixture; cooling the monomer mixture, concentrating the cooled mixture, dissolving in a suitable solvent cooled to nucleophilic substitution mixture, treating the cooled mixture containing the solvent suitable for nucleophilic substitution with u n compuestode amino-vinyl tertiary, to form a second reaction mixture; heating the second reaction mixture at a temperature sufficient to promote reaction without provocargelificación; remove any remaining solvent to provide a product containing material ypurificar material containing product to produce a device-forming monomer médicosextraíbles water.
