Abstract: A protective coating composition containing a polycaprolactone polyol and an aminoplast derivative is applied to a thermoplastic substrate to produce a thermoformable article having abrasion resistance, solvent resistance and weatherability.

Abstract: Improved surface conductivity and EMI shielding effectiveness at high frequencies are obtained in thermoplastic compositions by the incorporation therein of a novel, synergistic combination of conductive fillers.

Abstract: Novel modified polyetherimide esters are prepared from diols, dicarboxylic acids and a combination of polyoxyalkylene diimide diacids and dimer acid. These compositions have many excellent properties which make them particularly useful for extrusion and molding applications.

Abstract: Foamable low-modulus thermoplastic compositions are prepared by incorporating suitable chemical blowing agents in low-modulus polymers. Specifically, low-modulus copolyetherester compositions may be foamed by use of citric acid, sodium bicarbonate or mixtures thereof as blowing agents.

Abstract: Epoxy compounds are added to polycarbonate resin to reduce or eliminate the necessity of drying the resin prior to a foaming process.

Abstract: Improved copolyether ester elastomers having excellent melt and crystallization temperatures as well as improved compression set as compared to prior art copolyetheresters are prepared by incorporating therein hexahydrophthalic ester polymer blocks.

Abstract: Copolyetherester molding compositions comprising a copolyetherester and modifying combination of (i) an aromatic thermoplastic polyester and (ii) clay.

Abstract: The present invention provides a method and primer composition to increase the adherence of a polydiorganosiloxane-polycarbonate block copolymer lamina or layer to adjoining thermoplastic laminae or layers in a consolidated laminate or composite.

Abstract: Novel copolyetherester elastomer molding compositions are prepared from diols, diacids, poly(alkylene ether) glycol and caprolactone or polycaprolactone.

Abstract: Melt-processable polyamides are prepared smoothly and rapidly by interchange of diesters of dicarboxylic acids with diamines in a solventless melt phase process.

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: A modified thermoplastic molding composition having improved compatibility and mold releasability the composition comprising a thermoplastic polyester resin selected from the group consisting of polyethylene terephthalate, poly(1,4-butylene terephthalate), a co-polyester or any combination thereof and from about 0.1 to about 20% by weight based on the total composition of linear low density polyethylene. Optionally, the composition may have added thereto an effective amount of an aromatic polycarbonate for impact strength. The compositions may also contain an effective amount of at least one additive selected from the group consisting of fillers, reinforcing agents, nucleating agents, flow promoters, coloring agents, flame retardants, coupling agents and stabilizers.

Abstract: Improved copolyether ester elastomers having excellent melt and crystallization temperatures as well as improved compression set as compared to prior art copolyetheresters are prepared by incorporating therein dimer ester polymer blocks.

Abstract: Poly(butylene terephthalate) injected molded articles which contain small uniformly distributed amounts of amorphous carbon or graphite powder, or graphitic carbon in the form of fibers, or any combination thereof, are electroconductive and possess decreased tendency to accumulate charges of static electricity. Minor amounts of glass fibers, polycarbonate resins and rubbery impact modifiers improve the electroconductivity imparted by the carbon.

Abstract: Polymeric substrates, especially the polycarbonates, are coated with a photocurable coating mixture containing polyfunctional acrylates, acrylonitriles, and a photoiniator to produce scratch- and mar-resistant polymeric articles.

Abstract: Novel poly(etherimide esters) are prepared by reacting a diol, a dicarboxylic acid, a poly(oxy alkylene) diamine and a tricarboxylic acid having two vicinal carboxyl groups or the anhydride thereof.
