A polyester polymer including at least one polyoxetane block of repeating units derived from polymerizing at least one oxetane monomer having at least one pendant —CH2—O—(CH2)n— Rf group wherein said Rf group is partially or fully fluorinated is described. A preferred process for forming said polymer by reacting the hydroxyl terminated polymer with a polycarboxylic acid under appropriate conditions to form an ester linkage and then adding and reacting that product with polyester forming reactants.
