Abstract: The invention provides a thermoplastic elastomer composition that includes a resin component and an additive, in which the resin component includes a styrene-based block copolymer containing a covalently crosslinked part, and a polyolefin having a weight average molecular weight of 80,000 to 500,000, a content of the styrene-based block copolymer is 40%-95% by mass relative to the entire resin component, and a content of the polyolefin is 5%-60% by mass relative to the entire resin component; and the additive includes an acid-modified compound having a weight average molecular weight of 1,000 or more and less than 80,000 and having a functional group derived from a carboxylic acid- and/or its derivative, and/or a polyester compound, and a crosslinking agent capable of crosslinking at least one of the styrene-based block copolymer and the polyolefin.

Abstract: The invention provides a liquid crystal polymer particle which, when added to a resin film, can allow the resin film to be reduced in dielectric tangent with increases in surface roughness and linear coefficient of expansion of the resin film being suppressed. The liquid crystal polymer particle according to the invention, in which 80% by mass or more of the entire particle is flat, and a longer size, a shorter size, and a thickness defined below of a flat liquid crystal polymer particle satisfies the following conditions (A) and (B): (A) an elongation as the ratio of the longer size and the shorter size is 1.2 or more and 5.0 or less, (B) a degree of flatness as the ratio of the shorter size and the thickness is 1.2 or more.

Abstract: Disclosed are resin particles having excellent thermal decomposability and suitable hardness. The resin particles are cross-linked methacrylate resin particles obtained by polymerizing monofunctional methacrylate and polyfunctional methacrylate, wherein the blending amount of the monofunctional methacrylate is 60% by mass to 95% by mass and the blending amount of the polyfunctional methacrylate is 5% by mass to 40% by mass with respect to the total amount of methacrylate compound, being a raw material for the polymerization reaction; the number of carbon atoms in the ester substituent of the monofunctional methacrylate is 3 or less; and 5% mass reduction temperature of the cross-linked methacrylate resin particles as measured by thermogravimetric differential thermal analysis is 180° C. or more and 240° C. or less.
