Abstract:
A cured polyester composition, comprising:the reaction product of (i) at least one polyoxetane chemically bonded via an ester linkage to at least one polyester, said ester linkage being derived from the reaction of a hydroxyl group of said polyoxetane with a carboxylic acid group of a polycarboxylic acid or an anhydride thereof; said polyoxetane having repeat units derived from oxetane monomers having at least one pendant â€”CH2â€”Oâ€”(CH2)nâ€”Rf group, with each n being, independently, 1 to about 5; and each Rf being, independently, unsaturated, or a linear or branched saturated alkyl group of from 1 to about 20 carbon atoms with a minimum of 25% of the hydrogen atoms of said alkyl group being replaced by F, and optionally up to all of the remaining H atoms being replaced by I, Cl, or Br; and said at least one polyester being derived from an ester condensation reaction of at least one polycarboxylic acid or an anhydride thereof with at least one polyol or at least one cyclic ether, and (ii) an amino resin.
