A hydrophobic modified polyrotaxane has a cyclic molecule, a linear molecule including the cyclic molecule with piercing through the cyclic molecule, and blocking groups which are placed at both end terminals of the linear molecule to prevent the cyclic molecule from leaving from the linear molecule. The cyclic molecule is cyclodextrin, and each of all or a part of the hydroxyl groups in the cyclodextrin is modified with a hydrophobic modification group. A crosslinked polyrotaxane is formed by combining this hydrophobic modified polyrotaxane and a polymer through the cyclic molecule.

Abstract: In this grease composition, a grease produced by mixing at least one base oil selected from a mineral oil-type lubricant base oil, a synthetic lubricant base oil, and a biodegradable lubricant base oil with a thickener is compounded with a wax and water, and an additive such as a surfactant and a defoamer is optionally compounded therewith. A soap containing a calcium sulfonate complex is used as the thickener. A carnauba wax is preferably used as the wax. Since this grease composition is mainly composed of a grease and a wax, the grease composition extremely facilities its removal operation after application, is environmentally friendly, and has extremely excellent anti-corrosion performance. When the grease composition is used by being applied to a base material of an object to be welded, an effect of preventing the adhesion of welding spatters can be obtained.
