ABSTRACT:
A polishing pad is described as comprising, (a) particulate polymer which can be chosen from particulate thermoplastic polymer (e.g., particulate thermoplastic polyurethane), particulate crosslinked polymer (e.g., particulate crosslinked polyurethane and/or particulate crosslinked polyepoxide) and mixtures thereof; and (b) organic polymer binder (e.g., polyurethane binder and/or polyepoxide binder), which can bind the particulate polymer together, wherein said organic polymer binder can be prepared in-situ. The particulate polymer and organic polymer binder can be distributed substantially across the work surface the polishing pad, and the pad can have a percent pore volume of from 2 percent by volume to 50 percent by volume, based on the total volume of said polishing pad.
