Patent ID: 8247519

Claim:
A polymer comprising a fluoroether functionalized aromatic repeat unit represented by the structure (I) wherein, is a C 4 -C 12 linear alkylene diradical which can be branched or unbranched wherein one or more carbons can be replaced by ether oxygen, or a cyclic alkylene diradical wherein one or more carbons can be replaced by ether oxygen; Ar represents a benzene or naphthalene radical; each R is independently H, C 1 -C 10 alkyl, C 5 -C 15 aryl, C 6 -C 20 arylalkyl; OH, or a radical represented by the structure (II) with the proviso that only one R can be OH or the radical represented by the structure (II), X is O or CF 2 ; Z is H, Cl, or Br; a=0 or 1; and, Q represents the structure (Ia) wherein q=0-10; Y is O or CF 2 ; Rf 1 is (CF 2 ) n , wherein n is 0-10; and, Rf 2 is (CF 2 ) p , wherein p is 0-10, with the proviso that when p is 0, Y is CF 2 .
