Polishing pad and method for producing same

The purpose of the present invention is to provide: a polishing pad having a high polishing rate and excellent planarizing properties; and a method for producing the polishing pad. A polishing pad which has a polishing layer comprising a polyurethane resin foam, said polishing pad being characterized in that a polyurethane resin, which is a material used for forming the polyurethane resin foam, has an alkoxysilyl group represented by general formula (1) in a side chain thereof. (In the formula, X represents OR 1 or OH; and R 1 's independently represent an alkyl group having 1 to 4 carbon atoms.)

Surface treatment of particles and their use

The invention relates to the surface treatment of titanium dioxide, barium sulfate, zinc sulfide and/or lithopone particles, and to mixtures of these particles with special alkoxylated siloxanes for dispersion improvement in plastics.
