Document Type and Number:
Japanese Patent JP5005175
Kind Code:
B2
Abstract:
Peroxidic perfluoropolyethers having formula: X1-O(CF2O)n1(CF2CF2O)m1(CF2(CF2)zCF2O)p1 (O)h-X2 wherein: X1 and X2, equal to or different from each other, are chain end groups selected among -CF2COF, -COF, -SO2F; n1, m1, p1 and h are integers such that the number average molecular weight is in the range 700-100,000; z= 1 or 2; with the proviso that: the m1/n1 ratio is between 0.2 and 10; the p1/(n1+m1) ratio is lower than 0.05; the h/(n1+m1+p1) ratio is such that the PO content, defined as grams of active oxygen/100 g of compound, is in the range 0.8-4.5, preferably 1.4-3.8; the perfluorooxyalkylene units being statistically distributed along the polymeric chain.
