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. |
