Abstract:
1. A composition comprising an aryl perfluoropolyether which is a monofunctional aryl perfluoropolyether having the formula of R each of R R (a) J-O—(CF(CF (b) J (c) J (d) J (e) J (f) J (g) combinations of two or more thereof; and where the units with formulae CF J is CF c and d are numbers such that the c/d ratio ranges from about 0.01 to about 0.5; X is —F, —CF Z is —F, —Cl or —CF Z J e and f are numbers such that the e/f ratio ranges from about 0.3 to about 5; J j is an average number such that the formula weight of R J k is an average number such that the formula weight of R each Q is independently —F, —Cl, or —H; g, h and i are numbers such that (g+h) ranges from about 1 to about 50, the i/(g+h) ratio ranges from about 0.1 to about 0.5; J k′ is an average number such that the formula weight of R each R is independently —H, a halogen, —OH, —SO each R each R R M is H, Li, Na, K, Ca, or combinations of two or more thereof: a is 0 or 1; b is 0 Y is a divalent radical —CH n is about 1 to about 5; o is about 2 to about 5; t is equal to 6+u; u is any combination of 0, 2, 4, 6, 8, 10, 12, 14, 16; v is independently either 2 or 4; Rf where e, f, X, and Q are as defined above; p, q and r are numbers such that (p+q) ranges from 1 to 50 and r/(p+q) ranges from 0.1 to 0.05; each w is independently 2 to 45; Rf s is an average number such that the formula weight of R
