Title
(EN) SURFACE MODIFIED DIVINYLBENZENE RESIN HAVING A HEMOCOMPATIBLE COATING
(FR) RESINE DE DIVINYLBENZENE A SURFACE MODIFIEE POURVUE D'UN REVETEMENT HEMOCOMPATIBLE
Abstract
(EN)
A polymeric resin is disclosed in the form of beads or particles having a coating thereon which renders the resin blood compatible. The resin comprises divinylbenzene monomer which has a porosity, pore size, and surface area suitable for absorption of unhealthy components of blood, such as $g(b)-2-microglobulin.
(FR)
L'invention concerne une résine polymère se présentant sous forme de perles ou de particules recouvertes d'un revêtement qui rend la résine hémocompatible. Cette résine comprend un monomère de divinylbenzène dont la porosité, la dimension des pores et l'aire spécifique conviennent à l'absorption de composants sanguins nuisibles, tels que la $g(b)-2-microglobuline.
