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.

Vinyl-functional alcohols are silylated by reaction with a hydrolysable silyl hydride compound. The starting alcohol is heated and then combined with the silyl hydride and catalyst and allowed to heat exothermically. Cooling is applied when the conversion of vinyl groups is between 90-99%. In some embodiments, specified amounts of water are present. The cooling regimen and control of water content reduces certain side reactions, leading to greater yields to desired product.
