Title: A process for the preparation of non-ionic inorganic fluoro compounds
IPC: C01C3/20
Filed: 1963-06-17
Abstract: Oxidizers for liquid rockets, fuels such as hydrazine are compounds of formula F2N2Ox where x is 3-6 (see Division C1).ALSO:The compounds FN3, FNO3, FNO2, FONC, FClO3, FClO4, FCN, and F2N2Ox (x=3-6) are prepared by reacting F2 with the corresponding metal salt (viz. an azide, nitrate, nitrite &c.) in the presence of a "moderator" less reactive to F2 than are the metal salts. All the metals in periods 2-6 are specified, those in periods 2-4, especially alkali metals are preferred. The "moderator" may be a polar or non-polar liquid in which the metal salt is at least partially, preferably at least 1%, soluble, having a melting-point below 40 DEG  C., and is used in amount 0.5-200 parts per part metal salt.  Examples are alkanes, e.g. with 5-10 C atoms, haloalkanes with 1-8 C atoms, aromatic hydrocarbons with 6-12 C atoms, or their chlorinated derivatives, aliphatic ketones, ethers or amides, e.g. with alkyl groups having 1-8 C atoms, water, alkanols with 1-6 C atoms, or alkylene glycols with 1-6 C atoms, (specific examples given), or mixtures.  The reaction may be carried out in a Ni or polyethylene coated reactor at - 40 DEG  to +40 DEG  C. and under sub-, super-, or atmospheric pressure, employing stoichiometric amounts of reactants. F2 may be diluted with an inert gas, e.g.  He, N2. The product if gaseous is collected on a cold trap, and if non-gaseous by filtration crystallization, extraction and/or distillation. Metal fluorides are formed as by-products.

Title: Cross-linkable light-sensitive polymeric materials
Inventor: LARIDON URBAIN LEOPOLD
IPC: C08G63/688
Filed: 1964-06-15
Abstract: Light-sensitive polymeric materials comprise cross-linkable polymers containing azidosulphonyl groups attached to carbon atoms therein and groups, e.g. hydroxyl, pyridine, phenyl, lactam and ethylenically unsaturated groups, reactive with the photo-chemical decomposition products of the azidosulphonyl groups, either in the azidosulphonyl containing polymer or in a further polymer admixed therewith. The polymers may be modified natural or synthetic polymers, e.g. reaction products of sodium azide with chlorosulphonated styrene polymers and copolymers, reaction products of azidosulphonyl benzoyl chlorides with polyvinyl alcohol, vinyl alcohol/vinyl butyral copolymers and bisphenol A/epichlorohydrin condensates, and polycondensation products such as polyamides, polyureas, polyurethanes, polyesters, polysulphonamides and polysulphonates containing azidosulphonyl substituents.  Cross-linking may be enhanced by the presence of sensitizing compounds or substituent sensitizing groups in the polymer.  The condensation products may be prepared by interfacial condensation between an aqueous phase containing diamine or diol and alkali and an organic solvent phase, e.g. of chlorinated aliphatic hydrocarbons, hexane or aromatic hydrocarbons, containing diacid halides, diisocyanates, dihalocarbonylamino or dihalocarbonyloxy compounds. The products may be cast into films or coated on metals, paper, glass or plastics, and selectively exposed to form resists. In examples bisphenol A/epichlorohydrin condensates are reacted with (1-11 and 14-32) m-azidosulphonyl benzoyl chloride and (13) p-azido sulphonyl benzoyl chloride, sensitized with various sensitizers, and reacted with (42) l - p - chlorocarbonylphenyl - 3 - phenyl - 2-pyrazoline and m-azidosulphonyl benzoyl chloride; (12) a vinyl butyral/vinyl alcohol copolymer is reacted with m-azidosulphonyl benzoyl chloride; (33) p-chlorosulphonated polystyrene is reacted with sodium azide, and (34) admixed with poly-N-vinyl pyrrolidone; (35) polychloromethyl styrene is reacted with 2-chloro-5-azidosulphonyl benzoic acid, and admixed with (36) poly-N-vinyl pyrrolidone and (37) polystyrene; and interfacial polycondensation products are prepared from bisphenol A and (38) isophthalyl chloride and 5-azidosulphonyl isophthalyl chloride, (39) isophthalyl chloride, 5-azidosulphonyl isophthalyl chloride and pyridine-2,6-dicarboxylic acid chloride, (40) 5-azidosulphonyl isophthalyl chloride and (41) terephthalyl chloride, isophthalyl chloride and 5-azidosulphonyl isophthalyl chloride.ALSO:Azidosulphonyl benzoic acids may be prepared by reacting the chlorosulphonyl benzoic acids with sodium azide.  The products may be converted to the corresponding acid chlorides by refluxing with thionyl chloride.  In examples the (1) m- and (13) p-azidosulphonyl benzoic acids and benzoyl chlorides are prepared. In Example (35) 2-chloro-5-azido-sulphonyl benzoic acid is prepared by reacting 2-chloro-5-chlorosulphonyl benzoic acid with sodium azide.

Title: Coating method
IPC: C23C24/00
Filed: 1959-07-20
Abstract: A method of applying a fusible pulverulent coating material to the surface of an article, where either the article or the coating material is susceptible to deterioration as a result of heat, comprises rapidly heating the surface to above said deterioration temperature, such heating being limited in time so that the interior of said article remains at a temperature at least 20 DEG F. lower than the surface temperature, immersing the heated article in a fluidised bed of coating material to form a layer, and permitting the layer to coalesce.  The coated article may be re-heated to fuse the coating.  The process may be applied to copper and its alloys such as brass, iron and steel, magnesium, zinc, aluminium, wood, paper, paperboard, cotton, woven textiles, and plastics, which may be reinforced e.g. with fibreglass. Suitable coating materials include vinyl resins, nylon, polystyrene, epoxy resins, cellulose esters, silicones, bitumen or asphalt, shellac, wax, zinc, lead, porcelain and glass or mixtures thereof.  A priming coat of a substance which is liable to deterioration as a result of heat, e.g. a composition containing vinyl resins and alkylated methylol phenols may be applied: a consequence of the rapid heating is that curing of the primer does not take place before the final coating is applied. Specification 759,214 is referred to.ALSO:A method of applying a metal coating to the surface of an article, where either the article or the coating material is susceptible to deterioration as a result of heat, comprises rapidly heating the surface to above said deterioration temperature, such heating being limited in time so that the interior of said article remains at a temperature at least 20 DEG F. lower than the surface temperature, immersing the heated article in a fluidized bed of coating metal to form a layer, and permitting the layer to coalesce.
