摘要： Use in optical systems as liquids to transmit light at wave lengths lower than 250 nm, in particular at 157 nm, of perfluoropolyethers having the following formula: X1—O(CF2O)n(CF2CF2O)m(CF2CF2CF2O)p(CF2CF2CF2CF2O)q—X2 (I) wherein: the repeating units —CF2O—, —CF2CF2O—, —CF2CF2CF2O—, —CF2CF2CF2CF2O— are statistically distributed along the chain; —X1 and —X2 are perfluoroalkyl chain end groups equal to or different from each other, having formula —(CF2)zCF3 wherein z is 0 or an integer from 1 to 3; n, m, p, q are 0 or integers comprised between 1 and 100, with the proviso that: at least one among n, m, p and q is different from zero; the ratio between the oxygen atoms and the carbon atoms (O/C) is higher than 0.33; wherein the chlorine atoms, determined by 19F-NMR are substantially absent.

摘要： The invention pertains to a thermoplastic fluoropolymer composition comprising: at least one thermoplastic partially fluorinated fluoropolymer having a melt flow index (MFI) of less than 10 g/10 min, as measured according to ASTM D-1238 under a piston load of 5 kg polymer A; from 0.05 to 5% by weight of A at least one (per)fluoropolyether, polymer B; and from 0 to 10% by weight of A of at least one per(halo)fluoropolymer polymer C. The addition of a (per)fluoropolyether B and, optionally, of a per(halo)fluoropolymer C advantageously enables improvement of rheological behavior of thermoplastic partially fluorinated fluoropolymer A, making possible processing in less severe conditions and yielding final parts with outstanding surface aspect and good homogeneity and coherency. Still objects of the inventions are the process for manufacturing said thermoplastic fluoropolymer composition and the articles thereof.
