  • Multilayer polishing pads made by the methods for centrifugal casting of polymer polish pads
    Patent number: 10722997
    Abstract: A method for making a multilayer polishing pad includes rotating a cylinder about a central axis. The cylinder encloses in an interior space a single polymer mixture that phase separates under centrifugal force. The method also includes forming the polishing pad from at least some of a polymer formed after the polymer mixture has reacted. The method includes forming at least two distinct layers in the polishing pad by casting and gelling sequentially at least two different polymers.
    Type: Grant
