Abstract: The present invention provides a porous resinous oil-retaining article, containing lubricating oil, which is excellent in the utilization efficiency of the lubricating oil, has a high mechanical strength, and further allows the resin and the lubricating oil to be combined with each other according to a use and a specification. The present invention also provides a method of producing the resinous oil-retaining article. The resinous oil-retaining article comprises a resinous porous article having interconnected holes which are open to a surface of the resinous porous article; and an oil impregnated into the resinous porous article. The interconnected holes are formed by molding a resin containing a pore-forming substance into a molding and extracting a part of the pore-forming substance from the molding with a solvent which dissolves the pore-forming substance and does not dissolve the resin. An interconnected hole porosity of the resinous porous article is not more than 30%.

Abstract: A thermoplastic sulfur-polymer composite comprises a thermoplastic polymer, such as polyethylene and polystyrene; and a sulfur element. Such sulfur element functions as passive sulfur filler in this composite. The thermoplastic polymer is a polymer matrix; and the sulfur filler is dispersed in the polymer matrix. There is no chemical reaction occurs after the addition of the sulfur filler into the host polymer and no chemical bond formed between the polymer and the sulfur filler. The thermoplastic sulfur-polymer composite can be a nanocomposite by either adding certain nanofillers into the composite or making the sulfur filler as sulfur nanoparticles. With its similar physical properties and lower manufacturing costs, the thermoplastic sulfur-polymer composites are good alternatives of the respective pure polymers.

Abstract: A porous, resorbable and flexible dental surgical membrane (16) is made from chitosan having a viscosity average molecular weight of about 400,000 daltons up to about 2,000,000 daltons and has a thickness of from about 100 microns to about 0.5 mm. The membrane is easily insertable over a bone graft material site to confine the bone graft material (14) while allowing access to the bone graft material of blood and oxygen and applied medicaments through the membrane. The high molecular weight of the chitosan may be chosen so that the membrane will not dissolve or resorb in a human mouth for a protracted period, e.g., from about 12 to about 16 weeks. The membrane is made by dissolving medical grade chitosan in aqueous acetic acid, dispersing fine silica particles into the solution to form a slurry, depositing a film of the slurry on a support surface, evaporating liquid from the slurry sufficiently to form a coherent chitosan membrane having silica particles dispersed therein, and then dissolving the silica particles with a sodium hydroxide solution followed by a water wash to form the porous chitosan membrane.
