Abstract:
1. A process comprising combining in a pressure vessel a fluoroether functionalized aromatic diester or diacid and a C 4 -C 12 diamine and a catalyst to form a reaction mixture; sealing said pressure vessel, and heating said reaction mixture in an oxygen reduced atmosphere to a temperature of 225 to 275° C. under autogenous pressure; wherein the fluoroether functionalized aromatic diester or diacid is represented by the structure (III), 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 (II); R X is O or CF Z is H, CI, or Br; a=0 or 1; and, Q represents the structure (Ia) wherein q=0-10; Y is O or CF Rf and, Rf and, wherein the diamine comprises a C4-C12 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.
