Abstract: A wax composition comprises a microcrystalline wax or an oxidized microcrystalline wax, a metallic soap, an anti-oxidant and a liquid carrier.  Specified soaps are the palmitates and stearates of aluminium and the palmitates, stearates and oleates of magnesium, lead, zinc, calcium and barium.  Specified anti-oxidants are 2,21-methylene-bis (4-methyl-6-tert.-butylphenol), 2,21-thiobis (4-methyl-6-tert.-butylphenol), propyl gallate, N-phenyl-naphthylamine, a butyraldehyde-aniline condensation product, and a mixture of propyl gallate, butylated hydroxyanisole, citric acid and propylene glycol.  The liquid carrier is preferably non-aqueous and may be a mineral, vegetable, marine or synthetic oil, examples of each of which are given. Specification 722,724 is referred to.ALSO:A composition suitable for treating ropes or cords, or their constituent yarns or strands comprises a polyalkene, or an oxidized polyalkene, preferably polyethylene, a metallic soap, an anti-oxidant and a liquid carrier.  Specified soaps are the palmitates and stearates of aluminium and the palmitates, stearates and oleates of magnesium, lead, zinc, calcium and barium.  Specified anti-oxidants are 2,21-methylene-bis (4-methyl-6-tert.-butylphenol), 2,21-thio-bis (4-methyl-6-tert.-butylphenol), propyl gallate, N-phenyl-naphthylamine, a butyraldehyde-aniline condensation product, and a mixture of propyl gallate, butylated hydroxyanisole, citric acid and propylene glycol.  The liquid carrier is preferably non-aqueous and may be a mineral, vegetable, marine or synthetic oil, examples of each of which are given. Specification 722,724 is referred to.ALSO:The physical properties of ropes and cords are improved by treating the ropes or cords, or their constituent yarns or strands, with a composition comprising a polyalkene, an oxidized polyalkene, a microcrystalline wax or an oxidized microcrystalline wax.  The preferred polyalkene is polyethylene.  Suitable polyethylenes, oxidized polyethylenes, microcrystalline waxes and oxidized microcrystalline waxes are indicated in the Specification by reference to the trade names or Registered Trade Marks under which they are obtainable.  The treating composition preferably includes also a metallic soap, an antioxidant and a liquid carrier.  Specified soaps are the palmitates and stearates of aluminium and the palmitates, stearates and oleates of magnesium, lead, zinc, calcium and barium.  Specified anti-oxidants are 2,21-methylene-bis-(4-methyl-6-ter.-butylphenol), 2,21-thio-bis(4-methyl-6-ter.-butylphenol), propyl gallate, N-phenyl-a -naphthylamine, a butyraldehyde-aniline condensation product, and a mixture of propyl gallate, butylated hydroxyanisole, citric acid and propylene glycol.  The liquid carrier is preferably non-aqueous and may be a mineral, vegetable, marine or synthetic oil, examples of each of which are given. Examples are given of the treatment of nylon yarns, and certain physical properties of ropes made therefrom are recorded.  The process may be applied also in the manufacture of ropes or cords of polyethylene terephthalate, polyvinyl compounds, polyacrylates, regenerated cellulose, glass, manilla, jute, hemp or paper.  Specification 722,724 is referred to.
