Abstract:
A polyether copolymer characterized by strictly alternating poly(alkylene oxide) and aromatic diol monomeric repeating units having the structure: wherein R1 is sleected from the group consisting of alkyl, aryl, or alkylaryl groups with up to 18 carbon atoms, provided that R1 contains between 9 and 18 carbon atoms when R1 is an alkylaryl group; or R1 has the structure: wherein R5 and R6 are each independently selected from the group consisting of H, Br, I and straight and branched alkyl groups having up to 18 carbon atoms, R0 is selected from the group consisting of (â€”CH2â€”)d, â€”CH&boxH;CHâ€” and (â€”CHJ1â€”CHJ2), R15 is selected from the group consisting of (â€”CH2â€”)c, â€”CH&boxH;CHâ€” and (â€”CHJ1â€”CHJ2), wherein J1 and J2 are independently Br or I; c and d are independently between 0 and 8, inclusive; and Z is selected from the group consisting of H, a free carboxylic acid group or an ester or amide thereof; R7 is selected from the group consisting of alkylene groups containing from 1 to 4 carbon atoms; m is between about 5 and about 3,000; X2 is independently I or Br; and Y2 is between 0 and 2, inclusive.
