摘要： An apparatus for spraying molten plastics materials comprises a nozzle having an outer ring of passages for a combustible gas and a concentric inner ring of passages to which a coolant gas such as air and powdered plastics material in a stream of carrier gas are fed, the coolant gas and the powder being fed to alternate passages in the inner ring. The combustible gas may be a mixture of propane and oxygen or a mixture of acetylene and oxygen and the carrier gas may be air. In one example a steel lamp post is rotated in a horizontal plane and heated to about 240 DEG C. Nylon is then sprayed onto the post from a spray apparatus as described above which is at a distance of eight inches and is moved in a longitudinal path.

摘要： A polyester material contains as fire retardant a compound Ar(Br)m(Cl)nR or Ar(Br)m(Cl)nOR, where Ar is an aryl residue, m is 1 or more, n is 0, 1 or 2 and R is H or an alkyl, alkenyl, aryl or aralkyl group which may be halogenated, the compound containing at least two nuclear Br atoms per molecule, and providing at least 1.5 wt. per cent Br in the polyester resin. Suitable polyesters include commercial terephthalate polyesters and solution of glycol phthalate maleate in styrene. Suitable aromatic bromine compounds are tribromophenol, tetrabromo -, pentabromo -, pentabromo - ethoxy -, pentabromo - propoxy -, pentabromo - allyloxy-, and chloro-dibromo-allyloxy-benzene, and tribromo-, pentabromo-, tribromo-allyloxy-, and chloro - dibromo - toluene, and hexabromo - diphenyl ether, dibromo-diphenyl, dibromonaphthalene, 2:4 - dibromo - 1 - methyl - naphthalene and 1:5-dibromo-anthracene. The preferred Br content of the resin is 10-15 wt. per cent. There is preferably also incorporated in the polyester Sb2O3 amounting at least to 1 p.b.w. per 8 p.b.w. of bromo compound, preferably 0.5-1.5 p.b.w., per p.b.w. In examples various unsaturated polyester-styrene resins are mixed with a bromo-compound, benzoyl or MEK peroxide, and optionally also a Co naphthenate accelerator, CaCO3 filler and Sb2O3 and trixylyl phosphate as synergistic fire-retarding agents. A saturated polyester is mixed with pentabromotoluene and Sb2O3 (Example 10). The unsaturated resins are made into panels with or without glass fibre reinforcement. The bromo compounds used are tribromophenol, tribromotoluene, tribromophenyl allyl ether, pentabromophenyl allyl ether, pentabromophenol, pentabromotoluene, tetrabromobenzene and 4-chloro-tetrabromophenol.

摘要： The addn. of an organophosphite (=5 wt.%) to polymers contg. tris-(2,3-dibromopropyl)phosphate, greatly improves the flame-resistant properties of the polymers. Pref. 2 wt.% phosphite such as trialkyltriaryl- dialkylaryl- and/or diarylalkylphosphite is present. The total wt. of flame-preventive, incl. the phosphate, in the polymer is 3-25 pref. 5-15 wt.%. The phosphite is used in thermoplastic polymers.
