Abstract

[MOYEN POUR RÉSOUDRE LES PROBLÈMES] Polymère servant à empêcher l'adhérence de protéines obtenu en copolymérisant un monomère ayant un groupe amino tertiaire particulier et/ou un monomère ayant un groupe ammonium quaternaire particulier avec un monomère d'ester (méth)acrylique et un monomère soluble dans l'eau non ionique en quantités précises. [EFFETS] Le polymère servant à empêcher l'adhérence de protéines, même lorsqu'il est utilisé en traitementà faible concentration sur une courte durée, a l'excellente aptitude durable à empêcher des protéines d'adhérer sur des surfaces dures, par exemple de verres, de céramiques, d'acier et de plastiques, des surfaces molles, par exemple, de cheveux et de fibres, des surfaces de gels et des surfaces de lentilles de contact.
