Title: An n-substituted maleimide
IPC: C08K5/3415
Filed: 1962-01-23
Abstract: N-(4-Hydroxyphenyl) maleimide is polymerized with a mono-ethylenically unsaturated monomer or is homopolymerized. Homopolymerization is effected by refluxing in dioxan in the presence of 1, 11-azobisiso-butyronitrile. Copolymerization with styrene or ethyl acrylate is effected by refluxing a mixture of the two components in acetone in the presence of 1, 11-azobisisobutyronitrile.  The N-(4-hydroxyphenyl) maleimide may be used as a vulcanizing agent for natural or synthetic unsaturated rubbers, e.g.  Hevea, synthetic cis-polyisoprene, cis-polybutadiene, copolymers of butadiene with a -methylstyrene, acrylonitrile, methyl methacrylate, ethyl acrylate.ALSO:N-(4-hydroxyphenyl) maleimide, melting point 181-182 DEG C., is prepared by heating N-(4-acetoxyphenyl) maleimide in the presence of an alcohol and an acid catalyst.  The alcoholysis may be effected by using methanol and a small amount of sulphuric acid or p-toluene-sulphonic acid and the product recovered by distilling off the alcohol and recrystallising from isopropanol.  The N-(4-acetoxyphenyl) maleimide may be obtained by heating acetic anhydride, sodium acetate, and N-(4-hydroxyphenyl) maleamic acid.

Title: Process for the production of chlorinated hydrocarbons
IPC: C07C17/02
Filed: 1965-01-20
Abstract: 1,1,1,2- and/or 1,1,2,2 - Tetrachloroethane, with or without 1,1,2-trichloroethane, is made by subjecting a mixture of 1,2-dichloroethane and 1,1,2-trichloroethane, in a molecular ratio between 2 : 3 and 3 : 2 respectively, to pyrolytic chlorination at a temperature between 300-450 DEG  C. in the presence of no more than 0.3 mols chlorine per mol chloroethanes to give ethylenic products which are subjected to additive chlorination at temperatures no higher than 80 DEG  C., the amount of chlorine introduced being just sufficient to saturate the ethylenic products. The first stage is preferably effected in a fluidized sand bed.  If it is required to achieve simultaneous production of the trichloroethane, the ratio of dichloroethane to trichloroethane should be greater than 1.  In the second stage the additive chlorination is preferably catalysed, e.g. photochemically or by using metal chloride catalysts such as TeCl3. In the examples which relate to the preparation of the tetrachloroethanes and trichloroethane, the following are obtained in minor amounts as by-products: mono-, di- and tri-chloroethylene, pentachloroethane and perchloroethane.

Title: Improvements in or relating to electric cables
Inventor: BOOTH DAVID HUGH
IPC: H01B7/18
Filed: 1957-01-24
Abstract: 832,797. Cables. GLOVER & CO. Ltd., W. T., FIBREGLASS Ltd., and BRITISH RESIN PRODUCTS Ltd. Jan. 23, 1958 [Jan. 24, 1957], No. 2660/57. Drawings to Specification. Class 36. Lead sheathed cables subjected to internal pressure (e.g. gas- or oil-filled pressure cables) have the sheath reinforced by a glass-fibre-resin laminate covering comprising one or more layers of rovings, yarns, or weftless tapes of glass-fibre wound helically around the sheath together with a thermosetting resin which, when cured, has sufficient rigidity to limit local displacement of the glass fibre strands, due to internal pressure within the lead sheath, to that permitted by the elastic elongation of the strands, but is sufficiently elastic to allow " specified " bending of the cable without damage to the covering. By " specified " bending is meant the ability of the cable to withstand three bending cycles over a drum 30 times the diameter of the cable over its pressure resisting lead sheath. Suitable resins have a yield strength exceeding three thousands pounds per sq. inch, an elongation at yield of at least 5%, and may be of the unsaturated polyester, epoxy, or phenolic types, examples being given. The glass fibres may be impregnated either before or after application to the lead sheath, a preferred method being to apply alternately coatings of resin and lappings of glass rovings, three such layers with rovings lapped with alternate lays being followed by a lapping of regenerated cellulose tape, the resin then being cured by passing the cable through a heated bitumen bath at controlled speed. Alternatively, infra-red heating may be used. The application of such reinforcement to a gas-filled paper-insulated lead-sheathed cable with metallized paper and copper tape screens is described.
