  • Fluorinated monomers useful for preparing fluorinated polyquinoline polymers
    Patent number: 5344981
    Abstract: A new class of polymers is provided, as well as the monomers used for their preparation. The polymers provided in accordance with practice of the present invention include repeating units comprising one or more quinoline groups, wherein at least a portion of the repeating units includes a hexafluoroisopropylidene (6F) group or a 1-aryl-2,2,2-trifluoroethylidene (3F) group, or both.The hexafluoroisopropylidene group is referred to herein as a "6F" group and has the following structure: ##STR1## The "6F" group includes a tetravalent carbon atom bound to two trifluoromethyl moieties, with its other two bonds forming linkages in the polymer chain.The 1-aryl-2,2,2-trifluoroethylidene group is referred to herein as a "3F" group and has the following structure: ##STR2## wherein Ar' is an aryl group.
    Type: Grant
