Abstract
Dielectric compositions encompassing one or more poly(arylene ether) polymers are provided. The dielectric compositions have the repetitive structural unit: ##STR1## where n=0 to 1; m=0 to 1-n; and Y.sub.1, Y.sub.2, Ar.sub.1 and Ar.sub.2 are each a divalent arylene radical, Y.sub.1 and Y.sub.2 derived from biphenol compounds, Ar.sub.1 derived from difluoroarylethynes and Ar.sub.2 derived from difluoroaryl compounds. Where both Y.sub.1 and Y.sub.2 are derived from fluorene bisphenol, n=0.1 to 1. Such poly(arylene ether) polymers are employed with a variety of microelectronic devices, for example, integrated circuits and multichip modules.
