Abstract: 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.

Abstract: A side view type surface mounted light-emitting device includes a submount substrate that includes a mounting surface on one side surface and end through-holes formed at both edges of the mounting surface, a light-emitting element mounted on the submount substrate, first and second flat terminals formed on the mounting surface, and first and second through-hole terminals respectively formed on inner surfaces of the end through-holes at both edges of the mounting surface. At least one of the first flat terminal and the first through-hole terminal is electrically connected to one of n-side and p-side electrodes of the light-emitting element, and at least one of the second flat terminal and the second through-hole terminal is electrically connected to the other of the n-side and p-side electrodes of the light-emitting element.

Abstract: A polyrotaxane of high heat resistance contains a linear molecule, a cyclic molecule enclosing the linear molecule such that the cyclic molecule is skewered with the linear molecule, and 5 blocking groups disposed at both ends of the linear molecule. The cyclic molecule contains an aromatic ring having, on a side chain, a phenolic hydroxyl group. The polyrotaxane can be produced by dissolving, in a methanol-containing solvent, a linear molecule and a cyclic 10 molecule containing an aromatic ring having, on a side chain, a phenolic hydroxyl group, to yield a pseudo polyrotaxane in which the cyclic molecule encloses the linear molecule such that the cyclic molecule is skewered with the linear molecule; and dissolving the pseudo polyrotaxane and a blocking group 15 material in a solvent, to dispose blocking groups at both ends of the linear molecule.
