ABSTRACT:
Fluorinated prepolymers prepared by non-stoichiometrically reacting an alcohol having at least alcoholic carbons and at least one trifluoromethylene group attached to each alcoholic carbon with a fluorinated polycarboxylic acid having at least one methylene group between each carboxyl group and each fluorinated carbon. The reaction is carried out neat while the reactants are in liquid form and typically in a flowing, non-reactive atmosphere.
