  • Patent number: 8502401
    Abstract: A polymeric composition comprising a first polymer chosen from a poly(arylene ether) polymer including polymer repeat units of the following structure: —(O—Ar1—O—Ar2—O—)m—(—O—Ar3—O—Ar4—O)n- where Ar1, Ar2, Ar3, and Ar4 are identical or different aryl radicals, m is 0 to 1, n is 1 m; a polysulfone, a polyimide, a poly(etherketone), a polyurea, a polyurethane, and combinations thereof and a second polymer comprising a per(phenylethynyl) arene polymer derivative. Cured films containing the polymer can exhibit at least one of the following properties: Tg from 160° C. to 180° C., a dielectric constant below 2.7 with frequency independence, and a maximum moisture absorption of less than 0.17 wt %. Accordingly, the polymer is especially useful, for example, in interlayer dielectrics and in die-attach adhesives.
