Abstract
(EN)
A membrane comprising polymer particles fused together and pores between the fused particles, wherein: (a) the polymer particles have an average diameter of 0.1 to 5,000nm; (b) the membrane having a mean flow pore size of 5nm to 5,000nm; and (c) the membrane has been obtained by a process comprising curing a composition comprising: (i) a monomer; (ii) an organic polymerisation retardant; and (iii) an inert solvent; 0.149. The membranes are useful for detecting metal ions and for filtering and/or purifying biomoleculesand compositions comprising metal-ions.
(FR)
L'invention concerne une membrane comprenant des particules de polymère fusionnées ensemble et des pores entre les particules fondues, (a) les particules de polymère ayant un diamètre moyen de 0,1 à 5000 nm; (b) la membrane ayant une taille de pore d'écoulement moyenne de 5 nm à 5000 nm; et (c) la membrane ayant été obtenue par un processus comprenant le durcissement d'une composition comprenant : (I) un monomère; (ii) un retardateur de polymérisation organique; et (iii) un solvant inerte; le rapport pondéral du constituant (ii) au constituant (i) se situant dans la plage de 0,03 à 0,149. Les membranes sont utiles pour la détection d'ions métalliques et le filtrage et/ou la purification des biomolécules et des compositions comprenant des ions métalliques.
