    摘要: Porous infusible polymer (IP) parts are made by incorporating 0.2 to 10 volume percent organic fibers, preferably with short lengths, into the particulate IP, consolidating the mixture under pressure and optionally heating, and then “burning off” the fibers. After the fibers are burned off the resulting part has porosity in which the pores are elongated, usually retaining the shape of the organic fibers. When these parts are exposed to moisture (which they usually absorb) and then suddenly heated they tend not to blister from vaporization of the water. This makes them useful as parts for aircraft (jet) and other engines and other applications where sudden temperature increase may occur.

    摘要: A process for preparing a symmetrical dinitrodiphenyl ether from o- or p-nitrochlorobenzene or o- or p-nitrofluorobenzene comprising using a polar organic solvent, a potassium salt of a fatty carboxylic acid containing 2 to 20 carbon atoms or a potassium salt of an aromatic carboxylic acid containing 7 to 12 carbon atoms as catalyst, and either sodium or potassium carbonate to react with the p-nitrochlorobenzene. The reaction is carried out at from 150.degree. to 210.degree. C. until the o- or p-nitrochlorobenzene or o- or p-nitrofluorobenzene reacts.

    摘要: A bushing made from a thermoplastic polymer and circumferentially-oriented continuous high tensile modulus fibers is useful as a part for pumps and compressors and other similar types of apparatus. These parts may be useful at high temperatures and/or in very corrosive environments, often lengthen the time between required maintenance checks, and usually perform better than metal bushings under nonstandard operating conditions.

    摘要: A bushing-like part made from a fluoropolymer and circumferentially oriented continuous high tensile modulus fibers is useful as a part for pumps and compressors and other similar types of apparatus. These parts may be useful at high temperatures and/or very corrosive environments, often lengthen the time between required maintenance checks, and usually perform better than metal bushings under nonstandard operating conditions.
