Abstract
Abstract A fluorinated poly(naphthyl ether) having a repeat unit of the formula <IMAGE> wherein Y is (CF2)m, <IMAGE> <IMAGE> <IMAGE> m is an integer from 1 to 4, inclusive, and X is S, CO, SO2, O, P(C6H5), or C(OH)H. Such polymers are useful as low dielectric constant, low moisture absorption insulators for multilayered integrated circuit articles, especially in their crosslinked form.
