摘要:
A poly(arylene ether) composition containing a rubber-modified poly(alkenyl aromatic) resin, an unsaturated impact modifier and optionally an encapsulated fluoropolymer is disclosed. The melt strength of the composition, measured as hang time of an extruded tube, is especially suited for blow molding methods. The composition exhibits good melt strength, surface quality and/or sandability and is particularly useful for blow molding applications.

A process for reducing lip buildup during an extrusion of a polyphenylene ether composition comprises adding a linear low density polyethylene compound to the composition, wherein the amount of linear low density polyethylene compound is less than or equal to about 10 percent by weight based on the amount of polyphenylene ether compound in the composition.
摘要:
A non-halogenated, fire retardant, expandable poly (arylene ether)/polystyrene blends is produced by the method comprising, in a first step, forming a fire retardant mixture comprising a non-halogenated fire retardant, poly(arylene ether) resin and polystyrene resin by intimately mixing in melt; and in a second step, forming the non-halogenated, fire retardant, expandable poly (arylene ether)/polystyrene blend by intimately mixing in melt the fire retardant mixture with a blowing agent.
摘要:
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.
