Title: Stabilized olefin polymer compositions
IPC: C09D123/02
Filed: 1965-01-19
Abstract: A flame-resistant, non-corrosive metal coating composition comprises (1) a normally solid olefin polymer and, based on the weight of the olefin polymer, (2) from 1 to 80% by weight of a chlorinated hydrocarbon flame retardant, (3) from 0.1 to 5% by weight of a free radical generating cross-linking agent, (4) from 0.1 to 10% by weight of a hydrocarbon solvent solution of a hydrocarbon-soluble lead compound containing a sufficient amount of lead to inhibit the evolution of hydrogen chloride from the composition, and (5) from 0 to 6% by weight of a solid lead phthalate.  Preferred olefin polymers (1) are those of ethylene, propylene and butene-1, but copolymers of these monomers may also be used.  A long list of suitable comonomers is given.  Many conventional chlorinated hydrocarbon flame retardants (2) are specified, vinyl chloride polymers, especially polyvinyl chloride, being preferred.  The cross-linking agent (3) may be an organic peroxide, e.g. dicumyl peroxide, or an azo compound. The preferred hydrocarbon-soluble lead compounds (4) are lead octoate, naphthenate and tallate; also listed are lead hexanoate, heptanoate, oleate, linolenate and linolinate, and tetraethyl and tetraphenyl lead.  The usual hydrocarbon solvents, e.g. petroleum ether, are used.  Conventional fillers, pigments, antioxidants and stabilizers may be included in the composition as well as additional flame-proofing agents.  The solid lead phthalate (5) may be replaced by lead oxide or lead sulphate. The compositions are particularly useful for providing insulating coatings for wire, which coating may be effected by any known method.ALSO:Metal substrates, especially copper or tinned copper wire are coated with a flame resistant, non-corrosive metal-coating composition comprising (1) a normally solid olefin polymer and, based on the weight of the olefin polymer, (2) from 1 to 80% by weight of a chlorinated hydrocarbon flame retardant, (3) from 0.1 to 5% by weight of a free radical generating cross-linking agent, (4) from 0.1 to 10% by weight of a hydrocarbon solvent solution of a hydrocarbonsoluble lead compound containing a sufficient amount of lead to inhibit the evolution of hydrogen chloride from the composition, and (5) from 0 to 6% by weight of a solid lead phthalate (see Division C3).  The coating is effected at a temperature of from 160 to 200 DEG C. for from 1 to 20 minutes, the temperature being at least sufficient to induce crosslinking of the olefin polymer.  Conventional coating methods may be used. Other metal substrates mentioned are iron, steel and aluminium wire. Examples of olefin polymers are given.

Title: Manufacture of vat-dyestuffs
IPC: C09B7/00
Filed: 1928-01-25
Abstract: 284,288. I. G. Farbenindustrie Akt.- Ges. Jan. 27, 1927, [Convention date]. Thioindigoid dyes are obtained by condensing arylthioglycollic acids with o-diketones such as acenaphthenequinone, or isatin and its homologues or substitution products or alpha-derivatives, in presence of phosphorus pentoxide. It is advantageous to use a solvent or to mix the phosphorus pentoxide with a subdivided solid diluent to prevent agglomeration. According to examples, the condensation of the following pairs of components is effected in presence of chlorbenzene or dichlorbenzene and phosphorus pentoxide mixed intimately with silica :-1-chlornaphthalene-2-thioglycollic acid and isatin; naphthalene-2-thioglycollic acid and 5 : 7-dibromisatin; 6-methyl-4- chlorphenylthioglycollic acid and acenaphthenequinone. The salts of the thioglycollic acids may be used instead of the free acids. 1-Chlornaphthalene-2-thioglycollic acid is prepared from 1-aminonaphthalene-2-sulphonic acid by converting the latter, by Sandmeyer's reaction, into 1-chlornaphthalene-2-sulphonic acid, reducing after transforming the sulphonic acid into the sulphochloride, and finally coupling the resulting mercaptan with chloracetic acid.

Abstract: 1,202,684. Regenerating baths used in spinning acrylic threads. SOC. ITALIANA RESINE S.p.A. 17 Jan., 1969 [27 Jan., 1968], No. 2989/69. Heading B5B. Spinning baths used in making acrylonitrile polymer threads of 0À2 to 1À0 den. by extruding a solution of the polymer in dimethylformamide into a coagulating bath comprising cumene, D.M.F. and linear paraffins having 10 to 16 carbon atoms per molecule, and stretching the threads thereby formed in baths essentially comprising said paraffins, are regenerated by mixing together the solution enriched in impurities and D.M.F., which is discharged from the coagulating bath, with the solution enriched in cumene, D.M.F. and impurities, which is discharged from the stretching bath, subjecting the mixture to liquid/liquid extraction using D.M.F. as the solvent in order to separate a refined phase consisting essentially of paraffins and an extracted phase consisting essentially of cumene and dimethylformamide, recycling a fraction of the refined phase to the stretching bath after removing dimethylformamide therefrom by treatment with small proportions of water, recycling the remaining fraction of the refined phase as such to the coagulating bath, treating the extracted phase with water to separate an organic phase essentially comprising cumene and an aqueous phase containing D.M.F. and impurities, recycling the cumene phase to the coagulating bath, separating from the aqueous phase first water, and next D.M.F. by distillation, recycling the D.M.F. in part to to the extraction stage and in part to the coagulating bath, and utilizing the remaining dimethyl-formamide in preparing the spinning solution. The mixture of the solution discharged from the coagulating bath with the solution discharged from the stretching bath may be fed to an intermediate region between the top and foot of an extraction column, the D.M.F. extraction solvent being fed to the end of the column at which the refined phase is separated, so as to obtain an extracted phase essentially comprising cumene and D.M.F. and a refined phase essentially comprising paraffins. The D.M.F. used as solvent may contain 0À5 to 10% by weight of water. The aqueous phase containing D.M.F. and impurities may be freed from water first by distillation in vacuum and from D.M.F. next by a thin layer technique.

Abstract: Monoalkyldihalogensilanes are prepared by heating together silicon and a gaseous mixture of hydrogen and an alkyl chloride or bromide. The silicon may be used as such or in the form of alloys or mixtures with copper or other metallic catalysts.  The preferred method is to use the silicon in the form of a solid porous mixture of silicon and copper such as is prepared by the process of Specification 575,669, [Group III], and to pass the gaseous mixture of substantially equimolecular amounts of the alkyl halide and hydrogen over this mass at about 390 DEG  C.  In examples: (1) a mixture of dry hydrogen and methyl chloride is passed over a silicon-copper contact mass comprised of 80 per cent Si, and 20 per cent Cu at 390 DEG  C. at the rate of 40 ccs. hydrogen and 30 ccs. methyl chloride per minute.  The products were condensed in a mixture of dry ice and acetone and redistilled; (2) as in example (1) except that the gases were passed at the rate of 60 ccs. of methyl chloride and 50 ccs. of hydrogen per minute.
