    Abstract: Compounds R1OCOO(CH2)4OCOOR2, wherein R1 and R2 are saturated chlorine-containing aliphatic radicles with 6 to 18 carbon atoms in all, are plasticizers for synthetic resins. Resins mentioned are vinyl polymerizates, e.g. polyvinyl chloride, polyvinylidene chloride, polystyrene, polyvinyl esters of organic acids, polyacrylic compounds or interpolymerizates of such vinyl compounds, aldehyde and ketone resins, cellulose esters, e.g. nitrocellulose and cellulose esters of organic acids, and phenol- or maleic acid-modified colophony esters. Conventional plasticizers, fillers, stabilizers and dyestuffs may be present. The incorporation of the ester with the resin may be effected in the usual way, e.g. by kneading or rolling or the ester may be added to an aqueous emulsion of the resin. Generally 10-60 per cent of ester is present. The compositions may be used in lacquers and worked in the usual way to yield lamin , films, foils or bands, for sticking surfaces together, for coating wood, metal, fabrics or paper and for the preparation of cable compositions, oilcloths, artificial leather and floor coverings. In examples: (1) P.V.C. is plasticized with the bis-omega-chlorbutyl carbonate of butanediol-1,4 and in the remainder lacquers are made comprising together with conventional volatile solvents and the bis-omega-dichlorbutylcarbonate of butanediol-1.4 (2) pyroxylin; (3) a synthetic resin derived from cyclohexanone and methylcyclohexanone by caustic soda treatment, carbon black and pyroxylin; (4) crude castor oil and pyroxylin; (5) a U.-F. condensation product and pyroxylin; and (6) polystyrenes.ALSO:Compounds R1OCOO-(CH2)4OCOOR2 wherein R1 and R2 are saturated chlorine containing aliphatic radicles with 6 to 18 carbon atoms in all are obtainable by reaction of the bischlorcarbonic acid ester of butanediol-1,4 with monohydric saturated chlor-alcohols such as omega-chlorbutanol and its homologues or ethylene glycol mono-omega-chlorethyl ether, or by reacting chlor-carbonic acid esters of these chlor-alcohols with butanediol-1,4. They are plasticizers (c.f. Group IV (a). In an example (1) the bis-omega-chlor-butyl-carbonate of butanediol-1,4 is made by reacting butanediol-1,4 with chlor-butyl-chlor-carbonate.ALSO:Natural resins e.g. colophony and dammar, are plasticized with a compound R1OOCO(CH2)4 OCOOR2, where R1 and R2 are saturated chlorine-containing aliphatic radicles with 6 to 18 carbon atoms in all.

    Abstract: 1,228,921. Chlorinating ethylene polymers. BADISCHE ANILIN- & SODA-FABRIK A.G. 28 Aug., 1968 [29 Aug., 1967], No. 41123/68. Heading C3P. A chlorinated ethylene polymer is prepared by allowing gaseous chlorine to act on a finely particled compact ethylene polymer which has been obtained by high pressure polymerization and which has an average particle diameter with the range from 200 to 800 microns and a specific surface area of from 70 to 300 cm. 2 /g. in the absence of solvents and suspension agents. Suitable polymers are homopolymers of ethylene or copolymers of ethylene with one or more other singly unsaturated olefins e.g. propylene or n-butene. The ethylene polymer may have a molecular weight of 10,000 to 180,000 and a density of 0À880 to 0.938 g./cm. 3 . The chlorination may be carried out in a fluidized bed, a rotary kiln or a stirred vessel.

    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.
