Poly(arylene ether) polymers comprising a repeat unit of the structure:n n wherein m = 0 to 1.0, and n = 1.0 - m; and Ar 1 , Ar 2 , Ar 3 and Ar 4 are individually non-functionalized divalent arylene radicals are dielectric materials for use in microelectronic devices. Preferably said divalent radicals are selected from certain phenylene, biphenylene, triphenylene, naphthalene, anthracene, phenanthrene, 9,9-diphenylfluorene and dibenzofuran diradicals. |
