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.
