CA 2591921

The present invention provides blend water-swellable materials and hydrogels suitable for use in biomedical or other applications. The blend water swellable materials and hydrogels have at least one hydrophilic polymer and at least one other polymer or oligomer having both hydrophobic and hydrophilic recurring units where the blend phase separates and is opaque and immiscible in the presence of water. Methods of making these blend water-swellable materials and hydrogels are also described.

L'invention concerne des matériaux et hydrogels de mélange dilatables dans l'eau, destinés à être utilisés dans des applications biomédicales ou autres. Lesdits matériaux et hydrogels contiennent au moins un polymère hydrophile et au moins un autre polymère ou oligomère contenant à la fois des unités récurrentes hydrophobes et hydrophiles, la phase de mélange se séparant et étant opaque et immiscible en présence d'eau. L'invention concerne également des procédés de fabrication de ces matériaux et hydrogels.
