Extremely useful compositions for delineation of materials utilized in device applications have been found. These compositions include a polymer having segments that are at least 10 monomer units long of a first entity and segments again at least 10 monomer units long of a second entity. The monomer units are chosen so that each segment type provides a specific chemical characteristic to the polymer.
