Abstract
Fluorinated oligomers, polymers, and copolymers including poly[[1,1 ′-biphenyl]-4,4′-diyl[2,2,2-trifluoro-1-(trifluoromethyl)ethylidene]] and other compounds useful for high performance polymer, electronic, aerospace, coatings, and high temperature gas separation applications. Also provided are methods for synthesizing fluorinated polymer derivatives.
Claims64
A polymer consisting essentially of units of aromatic-based compounds, at least one of said aromatic-based compounds being substituted with at least one CF3 group, wherein said units are in the backbone of said polymer and do not contain elements other than carbon, hydrogen, fluorine, nitrogen and silicon.
A polymer selected from the group consisting of Compounds IIa, IIc, IId, IIe, IIf, IIg(1), IIg(2), IIh, IIi, and IIj, wherein a backbone of said polymer does not contain elements other than carbon, hydrogen, fluorine, nitrogen and silicon.
A method of preparing a fluorinated polymer, comprising polymerizing monomers consisting essentially of aromatic-based compounds having functional groups, at least one of said functional groups of said aromatic-based compounds being substituted with at least one CF3 group wherein said polymerizing is conducted via nickel(0)-catalyst coupling polymerization, whereby the backbone of said polymer does not contain elements other than carbon, hydrogen, fluorine, nitrogen and silicon.
A polymer comprising Compound IIa.
