    Abstract: 1,147,684. Self-extinguishing thermoplastic compositions. BADISCHE ANILIN- & SODAFABRIK A.G. 19 July, 1966 [21 July, 1965], No. 32374/66. Headings C3C and C3P. A self-extinguishing composition consists of (a) a normally solid thermoplastic polymer or copolymer of styrene or substituted styrene which comprises at least 50% by wt. of the styrene or substituted styrene and less than 50% of one other olefinically unsaturated compound having intimately incorporated therewith (b) an organic bromide having a plurality of bromine atoms attached to carbon atoms and the bromine atoms making up more than 40% by wt. of the bromide, in such an amount that the composition has 0À1-5% wt. of bromine, and (c) 0À01-5% by wt. on (a) of a polymer consisting of repeating units of formula where R 1 is R 7 or XR 7 , R 7 is a C 1-6 aliphatic hydrocarbon, a phenylalkyl or phenyl radical which may be substituted by 1-5 chlorine atoms or a C 1-4 alkyl or alkoxy group and X is -O-, -CO- or -COO-; R 2 to R 6 are H, Cl or a C 1-4 alkyl or alkoxy group; and n is 3-200. The (a) polymer may be polystyrene or a copolymer of styrene and acrylonitrile. The (b) bromide may be hexabromocyclododecane or tris-(2,3-dibromopropyl) phosphate. The (c) polymer may be a polymerized diphenylmethane or ethylbenzene. The composition may be made by dissolving the three constituents in methylene chloride. The composition may also contain 3-10% of a foaming agent which is a volatile organic compound which does not dissolve the (a) polymer and has a boiling point below its softening point e.g. pentane, and may be foamed, e.g. in film form, using steam.

    Abstract: 1,136,115. Olefin polymer compositions. BADISCHE ANILIN - & SODA - FABRIK A.G. 1 April, 1966 [2 April, 1965], No. 14445/66. Heading C3P. Moulding materials comprise ethylene polymers of molecular weight 360,000 to 1,000,000 and which are homopolymers or copolymers with not more than 40% of propylene, butene-1, 4-methylpentene-1 or octene-1 and 5 to 45 weight per cent of propylene polymers, based on the total ethylene and propylene polymers, the propylene polymer being a homopolymer or copolymer with up to 10% ethylene butene-1 or 4-methylpentene-1. The compositions may also comprise stabilizers, fillers, pigments, antistatic agents and flame retardants, and may be prepared by dry blending or solvent mixing to give moulding granulates or powders which may be moulded into sheets, pipes, sections and hollow articles. Examples describe compositions of linear polyethylene and polypropylene for moulding containers.

    Abstract: In a process for the production of homopolymers and copolymers of ethylene by polymerizing ethylene in the presence of preformed ethylene polymer and in the absence of other diluents and using catalysts containing chromium oxides at pressures of 5 to 100 atmospheres, the ethylene is allowed to act on a mechanically moved suspension of the catalyst in the molten ethylene polymer at temperatures between 130 DEG and 230 DEG C. In the examples, ethylene is polymerized in batches or continuously, alone or with the comonomers propylene or butene-1, and with a catalyst comprising chromium trioxide on an aluminium silicate carrier suspended in a molten polyethylene which may be waxy.
