摘要： A lubricant comprising a partially defluorinated graphite fluoride obtained by exposing a dispersion of raw material graphite fluoride to electromagnetic radiation, followed by the separation of the resulting partially degraded graphite fluoride. The partially defluorinated graphite fluoride is not only excellent in lubricating properties but also has excellent compatibilities with resins, greases and oils. The excellent compatibilities of the partially defluorinated graphite fluoride are effective in preventing the unfavorable deposition of the graphite fluoride in a liquid lubricant composition and advantageously lead to improvement in the moldability of any graphite fluoride-resin composition, thereby enabling the ultimate composition to exhibit excellent lubricating properties.

摘要： A method of preparing graphite fluoride such as (CF).sub.n or (C.sub.2 F).sub.n by heterogeneous contact reaction between a carbon material such as graphite or petroleum coke and fluorine gas at about 200.degree.-550.degree. C. In the gas phase of the reaction system, the total concentration of higher fluorocarbons having more than four carbon atoms formed by side reactions is controlled so as not to become above 3% by volume by, for example, condensation or catalytic decomposition of at least a portion of the higher fluorocarbons in the gas flowed out of the reaction chamber for recirculation. Such control is highly effective for prevention of rapid and violent decomposition of the graphite fluoride existing in the solid phase of the reaction system induced by sudden decomposition of the higher fluorocarbons in the reaction system to lower fluorocarbons.

摘要： A polymer-coated particulate inorganic material, e.g. graphite, graphite fluoride or molybdenum disulfide, is obtained by preparing a reaction system containing a liquid medium, fine particles of the inorganic material, at least one vinylic monomer which undergoes radical polymerization or copolymerization and a polymerization initiator and allowing the vinylic monomer(s) in the reaction system to undergo polymerization and to bond to the surfaces of the inorganic material particles by graft polymerization. To enhance the efficiency of graft polymerization to thereby realize uniform coating even when the inorganic material is very low in surface energy as typified by graphite fluoride, the pH of the reaction system is adjusted to a value ranging from 5 to 9 by adding alkali to the reaction system soon after the addition of the polymerization initiator or alternatively by treating the inorganic material with alkali in advance of preparation of the reaction system. The polymer-coated inorganic material can easily be shaped into a solid body by compacting, optionally with addition of a synthetic resin.

摘要： Graphite fluoride, such as (CF).sub.n or (C.sub.2 F).sub.n, in powder form coated with a vinylic polymer, e.g. polymethyl methacrylate, which is bonding to the surfaces of the graphite fluoride particles by graft polymerization. The polymer-coated graphite fluoride retains unique properties of graphite fluoride such as high lubricating ability, can readily be dispersed in water and organic liquids, and can readily be press-shaped with or without the addition of a synthetic resin powder. The polymer-coated graphite fluoride is prepared by dispersing graphite fluoride in powder form and at least one vinylic monomer which undergoes radical polymerization in a mixture of water and either a water-soluble organic solvent or a surface-active agent, and then adding a polymerization initiator to the aqueous dispersion. The polymerization reaction takes place even at room temperature and can be promoted by heating up to 70.degree. C.
