Abstract:
1. A polymer blend comprising a poly(alkylene arylate) and 0.1 to 10 weight percent based upon the total weight of the blend of a block copolymer having a blockiness index, B, in the range of 0.56 to 0.8, comprising a first block comprising a plurality of non-fluorinated alkylene arylate repeat units adjacent to one another; and a second block comprising a plurality of fluoroether functionalized alkylene arylate repeat units adjacent to one another; said non-fluorinated alkylene arylate repeat unit represented by Structure I wherein each R is independently H or C1-C10 alkyl, and R3 is C2-C4 alkylene which can be branched or unbranched; and, said fluoroether functionalized repeat units are represented by Structure II, wherein, Ar represents a benzene or naphthalene radical; each R is independently H, C with the proviso that only one R can be OH or the radical represented by the Structure (III); R X is O or CF Z is H, Cl, or Br; a=0 or 1; and, Q represents the Structure (IIa) wherein q=0-10; Y is O or CF Rf and, Rf
