Dielectric compositions encompassing one or more poly(arylene ether) polymers are provided. The dielectric compositions have the repetitive structural unit:where n=1 to 200, Y and Ar are each a divalent arylene radical, Y derived from bisphenol compounds of general formula HO-Y-OH, Ar derived from difluoro diarylacetylenes and/or ethynylated benzophenones of general formula F-Ar-F and Z is optionally hydrogen, a methyl group or derived from a monofluoro-benzophenone derivative of general formula Z-F. Such poly(arylene ether) polymers are employed with a variety of microelectronic devices, for example, integrated circuits and multichip modules. |
