Patent GB-834381-A (GB)
Title: Improvements in and relating to polymerization
IPC: C08F10/00
Filed: 1958-04-18
Abstract: A polymerization catalyst is prepared by irradiating a Ti tetrahalide (preferably TiCl4) in presence of a saturated hydrocarbon solvent (e.g. cyclohexane or decalin) together with means for removing free halogen such as ethylene or cyclohexene. Actinic light within the wavelength range of the absorption spectrum of the tetrahalide above 1800   is used.  Use of a mercury lamp is specified in the examples, but sunlight is also mentioned.  After irradiation, an inorganic Al salt such as AlBr3 may be added as co-catalyst.  It is stated that a reduced Ti alkyl chloride, e.g. cyclohexyl-TiCl2, may be the catalytic species produced by irradiation.  It is stated that irradiation of TiCl4 vapour with light in the range from the far ultra-violet to 4000   results in deposition of TiCl2 and/or TiCl3 as a finely-divided brown solid; ethylene or propylene may be present as halogen scavengers.  It is further stated that reduced titanium chlorides are formed on irradiation of a decalin solution of TiCl4.ALSO:a -Olefins, e.g. ethylene and propylene are polymerized by use of a catalyst comprising : Ti tetrahalide, e.g. TiCl4 which has been irradiated with actinic light, within the wavelength range of the absorption spectrum of the tetrahalide above 1800  , in presence of a saturated hydrocarbon, e.g. cyclohexane or decalin together with a halogen scavenger such as ethylene or cyclohexene.  An inorganic Al salt, e.g. AlBr3, is optionally used as co-catalyst; the activity of the irradiated material may be due to the formation of a reduced Ti alkyl chloride, e.g. cyclohexyl-TiCl2.  Methanol may be used in the isolation of the polymer.  It is stated that use of the above catalyst leads to polyethylenes of molecular weight 10,000-25,000, or 70,000-120,000 if the said cocatalyst is used; but the polypropylene produced in an example is said to be of low molecular weight.

Abstract: 663,889. Wave-guides. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. April 27,1950 [May 9, 1949], No. 12383/49. Class 40 (viii). A wave-guide for producing circularly polarized waves comprises a hollow metal guide 1 having a single conductive plate 2 extending from its inner surface towards its axis, the penetration of the plate into the guide increasing smoothly and gradually from nearly zero at its end to a maximum width in the middle and then decreasing again to near zero at its other end. If a linearlypolarized wave is fed into this guide with its electric vector forming an angle of 45 degrees with the plane of the plate 2 the wave will be transformed into a circularly-polarized wave if the length of the plate has been suitably chosen. In practice a slot is cut in the side of the guide and the plate is adjusted therethrough until optimum results are obtained. The plate is then soldered in position and the portion outside the guide removed. In the case of a guide with a circular cross-section the plate lies in a radial plane of the guide while in a guide of square cross-section the plate should lie along one of the diagonal planes.

Title: Polyurethane foams
Inventor: BONIN WULF VON
IPC: C08G18/63
Filed: 1963-03-29
Abstract: Polyurethane foams are prepared by reacting an organic polyisocyanate in the presence of a blowing agent, with a polyhydric polyalkylene ether prepared by effecting polymerization of one or more ethylenically unsaturated monomers in situ in a polyhydric polyalkylene ether. The polyhydric polyalkylene ether may be substantially linear and have a M.W. of 400-5000 and a hydroxyl content of 0.5-15%.  Suitable ethers may have graft polymers and/or mixtures of ethylenically unsaturated monomers dissolved in or bonded to the ether.  Unsaturated monomers may be: aromatic vinyl compounds, e.g. styrene, olefines, e.g. ethylene, propylene, 1-butylene, 2-hexene, 1,4-hexadiene, 1,3-butadiene, 3-pentene, vinyl esters, e.g. vinyl acetate or propionate, vinyl chloride, vinylidene chloride, arcyclic and methacrylic acids, acrylonitrile, polyvinyl compounds, e.g. triallyl cyanurate and glycol dimethyl acrylate.  Suitable polyhydric polyalkylene ethers are those obtained by condensation of ethylene oxide, propylene oxide, 1,2- and 1,3-butylene oxide, styrene oxide, epichlorohydrin and tetrahydro furan.  These alkylene oxides may be condensed with polyhydric alcohols and amines.  The monomer is preferably used in amount 1-60% by weight and the polymerization is preferably effected in the absence of oxygen with an initiator, e.g. organic oxide or azo compound, or redox systems, e.g. benzoyl peroxide-diethyl toluidine and ferrous-ferric iron systems, or high energy radiation.  The polyhydric polyalkylene ethers containing the polymerizate may be used in admixture with other compounds containing active hydrogen atoms, e.g. linear or branched polyesters and polyesteramides, unmodified polyhydric polyalkylene ethers and reaction products of amino alcohols, diamines, hydroxyamines with alkylene oxides or carboxylic acids. In a typical Example (1) vinyl chloride was polymerized in the presence of linear polypropylene glycol of M.W. 2000 and benzoyl peroxide and the thus modified polyether reacted with tolylene diisocyanate in the presence of triethylene diamine, dibutyltin dilaurate, polysiloxane and water to form a foamed polyurethane.
