A composition comprising poly(arylene ether) resin and a hydrogenated block copolymer of an alkenyl aromatic compound and a conjugated diene, wherein the hydrogenated block copolymer has up to about 20 percent residual pendant aliphatic unsaturation and at least about 30 percent residual in-chain aliphatic unsaturation.

Poly(arylene ether) compositions, articles thereof and methods of making them

An article includes a reinforced thermoplastic composition containing specific amounts of a poly(arylene ether), a homopolymer of an alkenyl aromatic monomer, a polyolefin, a hydrogenated block copolymer with a high styrene content, an unhydrogenated block copolymer, and glass fibers. The composition contributes very high stiffness and high impact strength to the article.

Articles and sheets containing glass-filled poly(arylene ether)-polyolefin composition

A poly(arylene ether)-polyolefin composition is prepared by melt-blending a poly(arylene ether), a poly(alkenyl aromatic) resin, a hydrogenated block copolymer of an alkenyl aromatic compound and a conjugated diene, and an unhydrogenated block copolymer of an alkenyl aromatic compound and a conjugated diene to form a first blend, and melt-blending the first blend and a polyolefin and additional hydrogenated block copolymer to form a second blend. A reinforcing filler and/or an ethylene/alpha-olefin elastomeric copolymer may, optionally, be added during formation of the second blend or in an additional step. Multiple mixing elements, low throughput, and high extruder rotations per minute may be used to achieve high energy mixing of the first and second blends. Compositions prepared by the method exhibit an improved balance of impact strength, stiffness, and heat resistance, as well as reduced variability of physical properties.

Method for the preparation of a poly(arylene ether)-polyolefin composition, and composition prepared thereby

A thermoplastic composition includes a poly(arylene ether), a poly(alkenyl aromatic) resin, a polyolefin, and a selectively hydrogenated block copolymer of an alkenyl aromatic compound and a conjugated diene having up to about 20 percent residual pendant aliphatic unsaturation and at least about 30 percent residual in-chain aliphatic unsaturation.

A method for specifying a multi-component composition without human intervention includes customer specification of at least two physical property limitations, and determination of a recommended composition meeting those limitations using a continuous model relating the physical properties to the compositional variables. The method may extend to supplying a multi-component composition by further including one or more of calculating the cost of the recommended composition, calculating the price of the recommended composition, formulating a contracted amount of the recommended composition, and billing for a contracted amount of the recommended composition.
