Novel poly(arylene ether) polymers have repeating units of the structure: <CHEM> wherein m = 0 to 1.0; and n = 1.0 - m; and Ar1, Ar2 and Ar3 are individually non-functionalized divalent arylene radicals. Preferably said divalent arylene radicals are selected from certain phenylene, biphenylene, triphenylene, naphthalene, anthracene, phenanthrene, 9,9-diphenylfluorene and dibenzofuran diradicals. The polymers are useful as low dielectric insulating layers in microelectronics. |
