Abstract

A new class of fluorinated arylacetylene compounds useful as monomers in the formation of polymers having low dielectric constant. These polymers, which are the reaction products of one of the fluorinated arylacetylene compounds, a diphenyl oxide biscyclopentadienone and, optionally, 1,3,5-tris(phenylacetylene)benzene, are useful in insulating microelectric device.
