    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.

    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 composition includes a poly(arylene ether) and a crosslinked block copolymer of an alkenyl aromatic monomer, such as styrene, and a conjugated diene, such as butadiene. The crosslinked block copolymer includes 50 to about 90 weight percent of repeating units derived from the alkenyl aromatic monomer. The composition exhibits improved ductility relative to a corresponding composition in which the block copolymer is not crosslinked.

    摘要: In a method of isolating a polymer blend from solution, a homogeneous solution including a poly(arylene ether), a poly(alkenyl aromatic), and a solvent is combined with an anti-solvent to form a dispersion containing solid particles. The solid particles have improved handling properties compared to particles formed from precipitation of the poly(arylene ether) alone.

    摘要: Soluble polymer resins are separated from a solution slurry with the use of a precipitation aid where the slurry contains the polymer resin in both a soluble form and a solid particulate phase. The precipitation aid absorbs onto the surface of the solid polymer resin particulates and is a suitable blend component for formulations of the polymer resin. The solution slurry may be concentrated and heated prior to precipitation of the polymer resin.
