"A covered wire having an inner conducting core and a cover impregnated with a material including a halogenated condensed nucleus cyclic compound, an incombustible plasticizer therefor, and an inert substance filling the pores and interstices of the cover to assist in retaining the said material on the wire in case of fire." "Diphenyl, acenaphthene or phenanthrene may be chlorinated or otherwise halogenated to be substantially flame proof in themselves and they form syrupy, viscous liquids and amorphous resin-like solid materials, depending upon the degree of halogenation. When added to the crystalline chloronaphthalene or other halogenated cyclic compounds, they yI61d very excellent flexible impregnating materials. The structureless or amorphous property of the plasticizers and the fact that they are syrupy, viscous or resin-like materials, prevents the chlorinated naphthalene or anthracene from cracking along the crystalline surfaces whenever the textile or wire is deformed, thus prevent ing the occurrence of any opening which would form a leakage path through which electricity might pass from the wire or which may weaken the coating and tend to lower its resistance to the action of flame."

"Of the poiy-moro-oleflnic resins, polybutene and polyvinylbutyl ether are In general suitable for all-around usage,, The others, requiring somewhat higher temperatures for decomposition into fugitive gas, are of course also applicable with appropriate materials requiring higher temperatures for vitrification. Included also with the foregoing are haloge.nated derivatives, and these may be substituted for or used in conjunction with the synthetic resins. Like such, they decompose completely without residue; they also have another important property, vi, as halogenated derivatives, one of the products of decomposition is a dry hydrogen halide. The presence of a small amount of HC1 or like halide aids the development of a dense structure through acceleration of diffusion processes at the high temperatures. Examples of these resins are : chlorinated polyethylene, fluorinated polyethylene, chlor-fluorinated polyethylene, the chlorinated diphenyls (these being commercially known as the "Aroclors"). These chlorinated diphenyls are available in molecular weights of a range such as from thin liquid to stiff resinoid solid. They are thermoplastic, and the low molecular weight type act as lubricants. In effect, the first group of resins alone or combinations of the first group plus the halogenated type constitute the base resins used in these mixtures. In some instances, such a halogenated resin can be used to provide the desired functions including that of lubricant. Also effective In this respect are the liquid polybutenes, that Is, poly butenes having molecular weights less than 1,000. The molecular weight of the poly-mon>olefinic resins may vary somewhat, but aside from the liquid usage Just mentioned, they may range in _-cneral about 2,.' to 2/,.' . Cv.kj.
