| titleOfInvention | Tetrafluoroethylene telomers |
| abstract | Telomers of the formula SF5(C2F4)nCl, where n is less than 12 are prepared by subjecting a mixture of tetrafluoroethylene and sulphur chloride pentafluoride to the action of heat in the absence of ultra-violet radiation. Telomerization may be effected at normal pressure, e.g. by passing the mixed vapours through a nickel tube heated to 200 DEG to 300 DEG C., and condensing the product in a series of traps, or at autogenous pressure in a sealed vessel, e.g. 150 to 250 atmospheres at 250 DEG C. Higher telomers may also be obtained when the mixture contains less than 3 molar per cent SF5Cl. Specification 877,961 is referred to.ALSO:Telomers of the formula SF5(C2F4)nCl, where n is less than 12, are prepared by subjecting a mixture of tetrafluoroethylene and sulphur chloride pentafluoride to the action of heat in the absence of ultraviolet radiation. Telomerisation may be effected at normal pressure, e.g. by passing the mixed vapours through a nickel tube heated to 200 DEG C. to 300 DEG C. and condensing the product in a series of traps, or at autogenous pressure in a sealed vessel, e.g. 150 to 250 atmospheres at 250 DEG C. The mixture should contain at least 3 molar per cent SF5Cl, lower concentrations giving higher telomers. Specification 877,961 is referred to. |
