Patent

CA 2630486

The present invention relates to a polymer bead material that are characterised by having pore sizes that can be pre-determined and that can be obtained with a narrow distribution of such pore sizes created by use of sacrificial filler materials within the polymer material. The invention also discloses processes for production of the material as spherical or approximately spherical beads or resins with predefined sizes. Also, the invention relates to the preparation of molecularly imprinted polymer materials that are created by the said method. Further the invention relates to the use of said polymer materials for separation, detection, catalysis or entrapment of chemicals, metal ions, inorganic compounds, drags, peptides, proteins, DNA, natural and artificial polymers, natural or artificial compounds, food or pharma products, viruses, bacteria, cells and other entities.

L'invention concerne des perles de polymère qui sont caractérisées en ce qu'elles présentent des dimensions de pores pouvant être prédéterminées et qui présentent une distribution étroite de ces dimensions de pores produites au moyen de matériaux d'apport sacrificiels dans le matériau polymère ; des procédés de production du matériau sous forme de perles ou de résines sphériques ou quasi-sphériques présentant des tailles prédéfinies ; la préparation de matériaux polymères à empreinte moléculaire produits au moyen dudit procédé ; l'utilisation de matériaux polymères pour la séparation, la détection, la catalyse ou le piégeage de substances chimiques, d'ions métalliques, de composés inorganiques, de médicaments, de peptides, de protéines, d'ADN, de polymères naturels et artificiels, de composés naturels et artificiels, de produits alimentaires ou pharmaceutiques, de virus, de bactéries, de cellules et d'autres entités.
