Method of producing structures using centrifugal forces

A process for producing a product, comprising: a) filling a mold (A) with a solution (E) so that substantially all of it is removed the air, the solution (E) comprising at least two components whose phases can be separated into at least two phases with one phase separation agent; b) rotating said mold (A) containing the solution (E) at a speed of rotation effectively in the presence of said separation agent to induce phase separation between at least two components at least we two phases for rotation with at least one of the phases (J) is deposited on an inner surface (K) of the mold (a); c) stabilizing the product molding at least one of the phases (J) deposited onto the inner surface (K) of the mold (A).
