摘要：
The present invention provides a spherical powder having properties, such as an excellent strength, toughness, and deformation recovery, and provides a method for producing same. The present invention provides: a spherical powder containing a crosslinked body formed having (A) a polyrotaxane in which both ends of a pseudopolyrotaxane, which are formed by inclusion of the opening of a cyclic molecule by threading therethrough with a linear molecule, are provided with a capping group so that dethreading of the linear molecule is prevented, in particular, a spherical powder having an average particle diameter of 0.5 to 1, 000 µm, preferably 1 to 500 µm, more preferably 1 to 300 µm, and still more preferably 1 to 150 µm; and a method for producing this spherical powder.
