Abstract
The present invention provides a polyrotaxane of high compatibility with silicones, such as silicone oil, a highly insulative polyrotaxane, and/or a material comprising said polyrotaxane. The present invention provides a polyrotaxane obtained by disposing blocking groups at both ends of a pseudopolyrotaxane, in which the opening in a cyclic molecule is clathrated in a skewered manner by a straight-chain molecule, so that the cyclic molecule does not escape, wherein the cyclic molecule comprises a first group represented by formula I (in formula I, X is a single bond or NH; n is 0 or 1; R is a straight-chain, branched, or cyclic alkyl group, alkenyl group, or alkynyl group comprising 12-20 carbon atoms, with some of the hydrogen in the alkyl group, alkenyl group, or alkynyl group being optionally substituted by an OH group, a CN group, or an NHgroup; and * is the position of the bond to the cyclic molecule).
