Abstract
A polyether copolymer characterized by strictly alternating poly(alkyleneoxide) and aromatic diol monomeric repeating units, wherein the combination of repeating units is effective to provide said polyether with a hydrophillic/hydrophobic ratio at which aqueous micelle self-assembly occurs.
Claims55
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 (—CH2—)d, —CH═CH— and (—CHJ1—CHJ2), R15 is selected from the group consisting of (—CH2—)c, —CH═CH— and (—CHJ1—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.
