Abstract: Compositions are provided including an uncrosslinked thermoplastic nitrogen-containing matrix material and composite particles distributed in the matrix material. The composite particles each include a chemical blowing agent particle encapsulated within a shell including an uncrosslinked thermoplastic material. The uncrosslinked thermoplastic material exhibits at least a certain minimum complex viscosity at a decomposition temperature of the chemical blowing agent particle. Also described are foam compositions and particles including the foam compositions, such as a sheet or multilayer construction. Composite particles are further provided. Methods of making the foam compositions are additionally described herein. Also, polishing pads, polishing systems, and methods of polishing a substrate are provided.

Abstract: A polishing pad includes a polishing layer having a first major surface and a second major surface opposite the first major surface. The polishing pad further includes a subpad, which is coupled to the polishing layer, and has a first major surface and a second major surface opposite the first major surface. At least 50% of the subpad, based on the total surface area of the first major surface of the subpad, is optically transparent.

Abstract: Articles and methods of making and using the articles are provided. The articles include inorganic agglomerates having an average dimension in a range from about 50 microns to about 2 mm. The porous agglomerates each include a network of carbon or silica, and metal oxide particles embedded in the network. Some agglomerates are capable of lowering a resonant frequency of an acoustic device when the resonant frequency is in a range from about 50 Hz to about 1500 Hz.

Abstract: Polishing pads include a polishing layer having a thickness and including a polymer having a working surface and a second surface opposite the working surface are described. In particular, polishing pads where the working surface includes a window, a plurality of precisely shaped pored, a plurality of precisely shaped asperities, and a land region are described. The window has a thickness different from the thickness of the polishing layer and includes a fluorinated polymer. The window has at least 20% transmission for any wavelength of light between 200 nm and 800 nm.

Abstract: Reaction mixtures, foams prepared from the reaction mixtures, articles containing the foams, and methods of making the foams are provided. The polymeric material in the foam is formed from a polymerizable composition that includes a di(meth)acrylate oligomer and a monomer having a single ethylenically unsaturated group. The foams are highly filled (e.g., at least 60 volume percent of the foam is the filler) and can be thermally conductive. Although the foams contain a large amount of filler, the foams can be compressed at least 40 volume percent with an applied pressure of 50 pounds per square inch (345 kiloPascals).
