ABSTRACT:
A method for preparing an open pourous polymer material, comprises forming of a polymer solution, addition of a porogen to the polymer solution and precipitation with water of polymer from the polymer solution, and the method then comprises removal of solvent and porogen from the polymer material wherein the precipitation is homogenous through that the water is in form of crystal water and that the crystal water is bonded to the porogen, wherein the porogen is a sugar hydrate. An open porous polymer material, a mixture comprising a sugar hydrate and a polymer solution, and a designed material, and uses thereof are also disclosed.
