Publication number: 20230123626Abstract: The present invention provides a crosslinked polymer composition exhibiting significantly improved elongation at break over conventional ones, and a polymer composition and a polyrotaxane, each of which can be used as a raw material of the crosslinked polymer composition. The polyrotaxane contains a linear molecule, a cyclic molecule, and a blocking group, wherein the cyclic molecule has a hydrosilyl group. The polymer composition contains the polyrotaxane and a polymer, wherein the polymer has a double bond on at least either a main chain or a side chain. The crosslinked polymer composition is produced by crosslinking of the polymer composition through chemical reaction between the hydrosilyl group of the cyclic molecule and the double bond of the polymer.Type: ApplicationFiled: December 2, 2020Publication date: April 20, 2023Inventors: Takanori NAKAI, Naoki IWASE, Naoyuki AKAHORI, Hideyuki IMAI, Hidekazu KURIMOTO, Makoto ISHIDA, Kohzo ITO, Rina MAEDA, Shota ANDO, Katsunari INOUE
