摘要： 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.

摘要： Polymeric foam layer having a thickness up to 25,700 micrometers, having first and second opposed major surfaces, and comprising foam features extending from or into the first major surface by at least 100 micrometers, and having a Tg in a range from −125° C. to 150° C., wherein the first and second opposed major surfaces are free of exposed internal porous cells (i.e., less than 10 percent of the surface area of each of the first and second major surface has any exposed porous cells) and wherein at least 40 percent by area of each major surface has an as-cured surface; and methods of making the same. Exemplary uses of polymeric foam layers described herein including a finishing pad for silicon wafers and vibration damping.

摘要： Coextruded polymeric layer having first and second opposed major surfaces, the coextruded polymeric layer comprising foam and the coextruded polymeric layer comprising features extending from or into the first major surface by at least 100 micrometers, the first major surface comprising a first material having a first percent elongation at break, the second major surface comprising a second material having a second percent elongation at break, wherein the first percent elongation at break is greater than 100 percent of the second percent elongation at break. Coextended polymeric layers described herein are useful, for example, in vibration damping applications (e.g., a vibration damping laminate comprising a kinetic spacer comprising the coextruded polymeric layers).
