POLYESTER WITH PARTIALLY FLUORINATED SIDE CHAINS

摘要

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.
