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 "3F" group and has the following structure: ##STR2## wherein Ar' is an aryl group. The "3F" group comprises a tetravalent carbon atom bound to one trifluoromethyl moiety and one aryl group with its other two bonds forming linkages in the polymer chain.
