摘要：
A method for inexpensively and easily manufacturing a polishing pad of excellent durability and polishing speed stability includes preparing a cell dispersed urethane composition by mechanical foaming, applying the cell dispersed urethane composition onto a base material layer, forming a polyurethane foamed layer having roughly spherical interconnected cells by curing the cell dispersed urethane composition, and regulating the thickness of the polyurethane foamed layer uniformly.
