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.

A composition includes a poly(arylene ether), a radial block copolymer having particular properties, and an optically enhancing additive. The composition exhibits an improved balance of ductility and optical clarity, making it useful in packaging applications, among others.
摘要:
A crosslinked block copolymer concentrate includes at least 80 weight percent of 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 concentrate may be blended with a poly(arylene ether) to form a composition with high ductility. Blends of the concentrate and poly(arylene ether) may also be formulated to be translucent or transparent.

摘要:
A poly(arylene ether) composition comprises a first poly(arylene ether) resin having an intrinsic viscosity greater than or equal to about 0.3 dl/g, as measured in chloroform at 25° C. and a second viscosity poly(arylene ether) resin having an intrinsic viscosity less than or equal to about 0.17 dl/g, as measured in chloroform at 25° C. wherein the composition is essentially free of plasticizers.
摘要:
A polymer blend may be prepared by melt kneading a composition that includes a poly(arylene ether), a polystyrene, and a carboxylic acid concentrate including a carboxylic acid compound and a polymer resin having a glass transition temperature or a melting temperature of about 30 to about 175° C. Using the carboxylic acid concentrate reduces the concentrations of styrene monomer and toluene in the polymer blend.
摘要:
A poly(arylene ether)/polystyrene blend may be prepared by melt kneading a carboxylic acid compound, a poly(arylene ether), and a polystyrene to form an intimate blend, and steam stripping the intimate blend, where melt kneading is conducted with a specific energy consumption of about 0.1 to about 0.3 kilowatt-hour per kilogram of blend. The method allows the formation of an intimate resin blend while minimizing the styrene monomer content of the final blend.
摘要:
A composition includes specific amounts of a poly(phenylene ether), a specific radial block copolymer, a polystyrene-poly(ethylene-butylene)polystyrene triblock copolymer, a specific organophosphate ester, a hydrocarbon resin, and benzoin. The composition exhibits a desirable balance of multiaxial impact strength, light transmittance, and optical clarity, and it can be used to mold a variety of articles including animal cages, ink cartridges, tubes, pipes, and pipe fittings.
