CA 2420683

Separation of a variety of analytes that are polar, nonpolar and ionic using functionalized polymeric media is disclosed. Preformed rigid particles of highly crosslinked homopolymer of polyvinylidene compounds are functionalized using the residual vinyl groups onto which monovinyl compounds are covalently bonded through polymerization. The functionalization imparts desirable surface properties for separation applications such as liquid chromatography and solid phase extraction.

L'invention concerne la séparation d'une variété d'analysats polaires, non polaires et ioniques par le biais de milieux polymères fonctionnalisés. Des particules rigides préformées à base d'homopolymère hautement réticulé de composés en polyvinylidène sont fonctionnalisées. On utilise pour cela les groupes vinyle résiduels, sur lesquels des composés monovinyle sont liés en mode covalent, par polymérisation. Il en résulte des propriétés de surface intéressantes pour les opérations de séparation, par exemple en chromatographie liquide et extraction de phase solide.
