Abstract

The present invention is directed to a self-conditioning polishing pad. The self-conditioning polishing pad comprises a water-insoluble polymeric foam matrix and water-insoluble polymeric foam particles within the foam matrix. The particles are coated with a water-soluble component over a portion of the surface area of the particle. The particles may have a diameter in the range of 5 to 2000 microns in diameter.
