UV curable fluorinated copolymer with improved adhesion property and a composition containing same, and their films containing same

摘要

PURPOSE: A UV curable fluorinated copolymer is provided to be used as a UV-curable transparent coating agent and to be suitable for processing a surface of various components requiring transparency, low refractivity and staining resistance. CONSTITUTION: A UV curable fluorinated copolymer is formed by copolymerizing one or more kinds of perfluorinated polyether-modified compounds represented by chemical formula 1: CF3CF2CF2-O-CF(CF3)-X-Y-X-CZ=CH2, CF3CF2CF2-O-CF(CF3)-Y-X-CZ=CH2 and one or more kinds of benzophenone-based acrylate monomers represented by chemical formula 2. In chemical formula 1, x is ester, urethane, ether or amide linker, Y is a C0-5 alkyl group, and Z is hydrogen, chlorine, fluorine or C1-5 alkyl group.
