In various embodiments the present invention comprises 2,4,6-trisubstituted-1,3,5-triazine capping agents comprising one, two, or three leaving groups as substituents with any remaining substituents being essentially inert to reaction with a nucleophilic group on a polymer or monomer, or reactive with a nucleophilic group on a polymer or monomer at a slower rate than any leaving group. The invention also comprises polymers or monomers with nucleophilic groups capped with a triazine moiety. Still other embodiments of the invention comprise processes for capping nucleophilic groups in a polymer or monomer which comprises combining and reacting the polymer or monomer with a triazine-comprising capping agent.

Triazine compounds, polymers comprising triazine structural units, and method

A composition useful in the manufacturing of plastic cookware includes a polyetherimide resin and an acidic additive selected from the group consisting of aliphatic carboxylic acids having a vapor pressure less than one atmosphere at 300&deg; C., aromatic carboxylic acids having a vapor pressure less than one atmosphere at 300&deg; C., and combinations comprising at least one of the foregoing acidic additives. In one embodiment, the composition further comprises an additional resin, such as a polyester resin. The acidic additive is effective in improving the mold release and increasing the melt flow of the composition. Articles including the composition and a method for preparing the composition are also described.

Polyetherimide composition, method, and article

Block copolyestercarbonates may be prepared by first conducting a reaction between at least one of resorcinol or an alkyl- or haloresorcinol and at least one aromatic dicarboxylic acid dichloride, preferably isophthaloyl dichloride, terephthaloyl dichloride or a mixture thereof, to produce a hydroxy-terminated polyester intermediate, and then conducting a reaction of the intermediate with a carbonate precursor, preferably in the presence of a dihydroxy compound such as bisphenol A. The products have excellent physical properties, including a high degree of weatherability. They may be blended with other polymers such as polycarbonates, poly(alkylene carboxylates), polyarylates, polyetherimides, and addition polymers to improve the weatherability thereof.

Weatherable block copolyestercarbonates and blends containing them, and method

Multilayer plastic composite articles comprise at least one poly (alkylene naphthalate) surface layer which is adherent to at least one surface of a substrate which is formed of a thermoplastic resin. Decorative layers can be located between the substrate and the poly (alkylene naphthalate) surface layers.

Multilayer plastic articles

Impact modified, compatibilized poly(phenylene ether)-polyamide compositions containing either a polybutene or an organosiloxane mixture give molded parts with good surface appearance, improved flow at high shear rate, and improved low temperature impact strength in comparison to control blends without added organosiloxane mixture or polybutene.

Poly(phenylene ether)-polyamide resin blends, method, and articles made therefrom

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

The present invention is directed to a unique poly(arylene ether)/polyetherimide composition having improved impact strength, as well as other improved mechanical and physical properties. This composition comprises: about 40 to about 90 pbw of a polyetherimide resin; about 8 to about 60 pbw of a functionalized poly(arylene ether) resin having a base titratable functionality level of at least 30 .mu.eq/g; and about 0.2 to about 35 pbw of a copolymer of an olefin and an epoxy-functionalized monomer; and may further include catalysts, gloss improvers, stabilizers, and other additives.

Poly(arylene ether)/polyetherimide blends and methods of making the same

The present invention is directed to a thermoplastic resin composition comprising one or more polyetherimide resins; one or more polyester resins; at least one epoxy compound having one or more epoxy functional groups per molecule in an amount effective to improve at least one of impact resistance, hydrolytic resistance, and tab-bending performance of a molded specimen of the composition; and optionally, at least one catalyst in an amount effective to improve at least one of impact resistance, hydrolytic resistance, and tab-bending performance of a molded specimen of the composition as compared to the same composition not containing the catalyst. It was unexpectedly found that the compositions exhibited enhanced heat, impact, hydrolytic resistance, and/or enhanced tab-bending performance over other compositions known in the art. In a preferred embodiment, the epoxy compound contains 3,4-epoxycyclohexylmethyl-3,4-epoxycyclohexanecarboxylate and the catalyst contains sodium stearate.

Polyetherimide resin/polyester resin blends having improved properties

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

Disclosed are transparent blends of a polyetherimide, at least one resin selected from the group consisting of polycarbonate resins, poly(ester-carbonate) resins, and polyarylate resins, and an effective amount of a catalyst to provide transparency to the blends. In addition to being transparent, the blends have good ductility as well as high flexural and tensile properties. The yellowness index of the compositions can be improved with the addition of a phosphite.

Transparent blends of polyetherimide resins

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.
