摘要: The invention relates to a method for manufacturing low-molecular-weight polytetrafluoroethylene, comprising: a) a first step of mixing high-molecular-weight polytetrafluoroethylene with at least one additive selected from the group consisting of ethers having formula R1—O—R2, wherein R1 and R2 are independently selected among C1-C10 straight or branched aliphatic group, C4-C10 alicyclic or heterocyclic groups, C5-C10 aromatic or heteroaromatic groups; (per)fluorinated vinyl ethers; (per)fluorinated olefins; and optionally substituted aromatic hydrocarbons, and b) a second step of irradiating the so obtained mixture with ionizing radiation, said second step b) being carried out substantially in the absence of oxygen.

摘要: A method for the manufacture of perfluorinated compounds is herein disclosed. In particular, the method is useful for the manufacture of perfluorooxyalkyl carboxylic acid salts which can be used as surfactants. The method envisages the fluorination or a fluoroformate of an alcohol comprising a —CH2OCH2-moiety at a temperature equal to or higher than 20° C. and allows obtaining high yields and selectivity.
