Abstract:
Conductive thermoplastic having high EMI shielding effectiveness comprise a thermoplastic condensation polymer and incorporated therein a synergistic combination of metal flake and conductive metal or metal coated fiber.
Abstract:
Disclosed are flame retardant polyetherimide ester compositions comprising: (i) at least one polyetherimide ester resin; and (ii) a flame retardant effective amount of a mixture comprising (a) at least one polyphosphonate ester, and (b) at least one ammonium polyphosphate.
Abstract:
Compositions are provided which comprise a first polyester resin (A) which comprises the reaction product of at least one straight chain, branched, or cycloaliphatic C2-C10 alkane diol or chemical equivalent thereof, and a cycloaliphatic diacid or chemical equivalent thereof; and (B) an aromatic polycarbonate resin, an aromatic polyester carbonate resin, an aromatic dihydric phenol sulfone carbonate resin, or a mixture of any of the foregoing. These compositions are transparent and homogeneous. They exhibit a significantly higher stiffness than the individual components, retain excellent impact strength and are UV radiation stable. Also provided are modified compositions as above which optionally include an additional polyester resin which may be the same as or different than the first polyester resin.
Abstract:
Compositions comprising a high molecular weight polyester resin or mixture of such resins, combined with an effective amount of a thermoplastic elastomer, with relatively high loadings of fillers selected from zinc oxide, barium sulfate, zirconium oxide, zirconium silicate, strontium sulfate or a mixture of any of such fillers, provide highly dense thermoplastic molded articles with improved impact strength and properties suitable to replace ceramics and filled thermosets in many important applications.
Abstract:
Novel thermoplastic elastomeric molding compositions comprising a blend of a thermoplastic elastomeric polymer and a high molecular weight thermoplastic polyester.
Abstract:
Copolyetherester molding compositions comprising a copolyetherester and modifying combination of (i) an aromatic thermoplastic polyester and (ii) clay.
Abstract:
Compositions are provided which comprise a polyester resin which comprises the reaction product of at least one straight chain, branched, or cycloaliphatic C2-C10 alkane diol or chemical equivalent thereof; and a cycloaliphatic diacid or chemical equivalent thereof; and a poly(ether ester) elastomer, a poly(etherimide ester) elastomer, a copolymer elastomer comprising (ether ester) monomers and (etherimide ester) monomers, a copolymer comprising ethylene and one or more comonomers copolymerizable therewith to provide a solid copolymer, or a combination of any of the foregoing. These compositions have excellent tensile properties.
Abstract:
Novel thermoplastic molding compositions having excellent stress-strength characteristics, particularly low temperature impact strength, comprising an admixture of a thermoplastic elastomer, a thermoplastic polyester, a modifier resin and, optionally clay.

Abstract:
Cette invention concerne des compositions comprenant une résine polyester qui contient le produit de réaction d'au moins un diol alcane C2-C10 à chaîne linéaire, ramifiée, ou cycloaliphatique ou d'un équivalent chimique de ce dernier et d'un diacide cycloaliphatique ou d'un équivalent chimique de ce dernier; un élastomère de poly(éther ester), un élastomère de poly(étherimide ester), un élastomère de copolymère comprenant des monomères d'(ether ester) et des monomères d'(étherimide ester), un copolymère comprenant de l'éthylène et un ou plusieurs comonomères pouvant être copolymérisés avec ce dernier pour produire un copolymère solide, ou une combinaison de n'importe lequel de ces derniers. Ces compositions présentent d'excellentes propriétés mécaniques à la traction.
