12 Claims

1. A polyrotaxane comprising capping groups each locating at each end of a pseudopolyrotaxane, which has a linear molecule and a cyclic molecule(s) in which the linear molecule is included in a cavity (cavities) of the cyclic molecule(s) in a skewered manner, in order to prevent the dissociation of the cyclic molecule(s),

wherein the cyclic molecule comprises a first group represented by following formula I,

wherein X represents a single bond or NH;

n represents 1;

R represents a linear, branched or cyclic alkyl group, alkenyl group or alkynyl group having 12 to 20 carbon atoms wherein a part of hydrogens in the alkyl group, alkenyl group or alkynyl group may be substituted with an OH group(s), a CN group(s) or an NH₂group(s); and

* represents the position bound to the cyclic molecule,
