    摘要: A poly(arylene ether) copolymer is the product of oxidative copolymerization of monomers including a monohydric phenol and a dihydric phenol. It has an intrinsic viscosity of about 0.04 to about 0.15 deciliter per gram and, on average, about 1.8 to about 2 hydroxyl groups per molecule. The poly(arylene ether) copolymer is enriched in low molecular weight copolymer chains and copolymer chains that include a terminal unit derived from the dihydric phenol.

    摘要: A method is disclosed for preparing carborane-siloxane polymers directly from carborane which comprises reacting and polymerizing a dilithio salt of a carborane with a bis-halo-ended siloxane. This novel method offers the advantage of eliminating the expensive and time-consuming preparation of certain monomer intermediates of carborane employed in the preparation of carborane-siloxane polymers.

    摘要: A composition includes at least 15 weight percent of a low intrinsic viscosity, bifunctional poly(arylene ether) and at least 20 weight percent of a nonhalogenated solvent. The bifunctional poly(arylene ether)s are substantially and unexpectedly more soluble than their monofunctional analogs. The compositions are useful as concentrates to add bifunctional poly(arylene ether)s to thermosets.

    摘要: A poly(arylene ether) may be fractionated into higher and lower molecular weight fractions by forming a mixture that includes a poly(arylene ether) starting material, a first solvent that is dichloromethane, bromochloromethane, dibromomethane, or a mixture thereof, and a second solvent different from the first solvent having a Hildebrand solubility parameter of about 16 to about 22 megapascal1/2. The mixture separates into fractions containing higher and lower molecular weight poly(arylene ether)s.
