ABSTRACT:
A process for making a fluorinated copolymer is disclosed. The process comprises polymerizing a monomer to form a polymer and then terminating the polymerization by adding a perfluorinated alkyl chlorosilane to the polymer. The perfluorinated alkyl chlorosilane reacts with the polymer to form a copolymer having a fluorinated terminal portion thereon.
