Abstract
Presently described are articles, such as optical displays and protective films, comprising a (e.g. light transmissive) substrate having a surface layer comprising the reaction product of a mixture comprising a non-fluorinated binder precursor (e.g. of a hardcoat composition) and at least one polymerizable perfluoropolyether polymer. The resulting cured surface layer can advantageously exhibit low lint attraction in combination with low surface energy. Also described are one-step and two-step methods of synthesizing perfluoropolyether polymers having polymerizable ethylenically unsaturated groups.
