A composition is provided which comprises a functionalized poly(phenylene ether) resin, poly(arylene sulfide) resin, epoxy functional alpha-olefin elastomer, elastomeric block copolymer, and a metal salt. The composition is preferably prepared by premixing a poly(phenylene ether) resin with an organic acid and a vinyl aromatic-diene block copolymer to form a premix, and then compounding the premix with an epoxy functional alpha-olefin elastomer, a poly(arylene sulfide) resin and a metal salt of an organic acid. The composition has enhanced levels of mechanical properties such as impact strength, and is suitable for making molded articles such as vertical automotive body panels.

Functional poly(phenylene ether)/poly(arylene sulfide)/epoxy function alpha olefin elastomer/elastomeric block copolymer/metal salt compositions and process for making thereof

Improved thermoplastic compositions that are resistant to die beard growth are described herein, comprising poly(phenylene ether) resins, polyamide resins and an amount of a beard growth reducing agent selected from the group consisting of non-elastomeric polyolefin resins, partially fluorinated polyolefins, and mixtures of non-elastomeric polyolefin resins and partially fluorinated polyolefins, effective for inhibiting beard growth. The compositions may further comprise at least one impact modifier, flow promotor or filler.

Compositions of poly(phenylene ether) and polyamide resins, which

Compositions are provided for compatibilized blends comprising compatibilizing poly(phenylene ether) resins and epoxy-functional polyolefins that exhibit improved resistance to delamination while providing high impact strength and other improved physical properties. Articles made from the compositions are useful for automotive lighting and under hood components.

Compositions of poly(phenylene ether) resins and epoxy-functional

Polymer blend compositions comprise (a) a polyphenylene ether polymer, (b) a polyphthalamide comprising the reaction product of (i) hexamethylene diamine or a mixture of hexamethylene diamine and trimethylhexamethylene diamine, and (ii) terephthalic acid, and optionally (iii) at least one acid selected from the group consisting of isophthalic acid and adipic acid, provided that a mixture of said diamines is employed if reactant (iii) is absent, and (c) at least one compatibilizer. The compositions may further include an aliphatic polyamide and/or an impact modifier.

Compatibilized blends of polyphenylene ether and polyphthalamide

Compositions are provided which comprise a poly(phenylene ether) resin, a poly(arylene sulfide) resin and an ortho ester compound. The compositions can further comprise compatibilizing agents and reinforcing fillers to provide compositions that exhibit low flash molding characteristics. Articles molded from these compositions are useful in the electrical connector industry.

Compositions of poly (phenylene ether), poly (arylene sulfide) and ortho

Compatibilized blends of poly(phenylene ether) resins and polyester resins are provided from nucleophile containing poly(phenylene ether) resins and polyester resins and compatibilizer compounds to afford articles having good impact, ductility and tensile properties. The compositions may further comprise impact modifiers, metal salts, reinforcing agents, flame retardants and flow promoters. Articles made from the compositions are useful for automotive components. Polymers chain extended with multifunctional orthoesters are claimed.

Compatibilized blends of poly(phenylene ether) resins and polyester resins are provided from nucleophile containing poly(phenylene ether) resins and polyester resins and compatibilizer compounds to afford articles having good impact, ductility and tensile properties. The compositions may further comprise impact modifiers, metal salts, reinforcing agents, flame retardants and flow promoters. Articles made from the compositions are useful for automotive components.

Thermoplastic compositions comprising polyphenylene ethers and polyesters, impact-modified by glycidyl (meth)acrylate grafted EPDM and compatibilized by an aromatic polycarbonate exhibit high impact strength alone and when combined with other impact modifiers. Their shear sensitive viscosity properties makes them uniquely suitable for extrusion and blow molding applications.

Olefinic impact modifiers for compatible blends of polyphenylene ethers

Resinous compositions comprising blends of linear polyesters such as poly(butylene terephthalate) with nitrile rubbers have very high impact strengths. The blends may also contain other polymers such as elastomers free from nitrile structural units, addition polymers of olefins or chlorinated olefins, or polylactones; such other polymers frequently improve properties such as gloss and low temperature impact strength.

Linear polyester resin blends with high impact resistance

Sulfonated polyimides and polyamic acids, particularly polyetherimides, are prepared by reacting the unsulfonated polymer with a mild sulfonating agent. Illustrative sulfonating agents are the complexes of sulfur trioxide and trialkyl or triaryl phosphates, especially the sulfur trioxide-triethyl phosphate complex having a molar ratio of sulfur trioxide to triethyl phosphate of 2:1.
