Abstract: A resin composition is provided. The resin composition includes a rigid polymer resin, a functionalized polyrotaxane, and (optionally) a core-shell polymer. The resin composition may be cured to form a cured thermoset resin. The cured thermoset set has improved mechanical properties relative to a reference cured thermoset. A method of preparing a cured article of the curable resin composition is also provided. The method includes providing the curable resin composition and curing the curable composition.

Abstract: Hybrid organic/inorganic coating compositions of nanometer thickness are described, where the organic layer is a clay-containing layer comprising a clay and a hydrophilic polymer and the inorganic layer is a metal-containing layer comprising a metal with a refractive index greater than 1.5, where the coating compositions allow for the generation and tenability of iridescent color through control of the coat thickness.

Abstract: An electroconductive polymer composition comprises a curable liquid thermosetting resin matrix; conductive nano-fibers such as carbon nano-tubes, carbon nano-fibers, metallic nano-fibers or non-conductive nano-fibers with an electrically conductive coating; and a particulate non-conductive phase discontinuously dispersed throughout the thermosetting matrix. The conductive nano-particles are dispersed throughout the matrix whereby when the thermosetting resin is cured, a percolation threshold is established within the thermoset matrix. The particulate non-conductive phase is selected from thermoplastic resin powders or exfoliated particles of nano-clay intercalated with the liquid thermosetting resin.

Abstract: The object is to provide a brush which does not easily damage metal during contact therewith. The present invention can provide a brush formed using polyacetal-containing filaments, in which the flexural rigidity per filament is 1 to 100 ?g·m2/yarn.
