F. and 27 psi using aqueous morpholine at a concentration of 50 ppm.

Abstract: A poly(aryl ether sulfone) blend comprising (a) from about 25 to about 99 percent by weight of a poly(biphenyl ether sulfone) and (b) from about 1 to about 75 percent by weight of a second poly(phenylene ether sulfone).

Abstract: A poly(aryl ether sulfone) blend comprising (a) from about 25 to about 99 percent by weight of a poly(biphenyl ether sulfone) and (b) from about 1 to about 75 percent by weight of a second poly(aryl ether sulfone) comprising bisphenol A moieties.

Abstract: A poly(aryl ether sulfone) blend comprising (a) from about 25 to about 99 percent by weight of a poly(biphenyl ether sulfone) and (b) from about 1 to about 75 percent by weight of a second poly(phenylene ether sulfone).

Abstract: A continuous plastic laminate having improved stiffness at use temperature, comprising at least three melt coextruded sheets, each comprising a thermoplastic polymer or polymer blend, the outside sheets having a higher stiffness at use temperature than at least one inside sheet.

Abstract: Described herein is a frozen food tray/cookware formed from a laminate, said laminate comprising at least three sheets made from a thermoplastic resin, wherein the inside sheet is made from an amorphous thermoplastic resin having a lower use temperature than the outside sheets, said amorphous thermoplastic resin being at least partially crystallizable at said lower use temperature.

Abstract: A serving tray suitable for institutional use and characterized by excellent physical and mechanical properties, including impact resistance and resistance to water spotting. The tray comprises a blend of a sulfone, styrene and a polycarbonate.

Abstract: Described herein are laminates formed from a layer of a polyarylate sheet and a layer of an aromatic polycarbonate, a polyester, or mixtures of these resin sheets. These laminates are suitable for use in glazing applications.

Abstract: A metal plated poly(aryl ether) containing article, said poly(aryl ether) comprising a blend of a poly(aryl ether) polymer, a styrene and/or acrylic copolymer and a compatibilizing amount of a polyhydroxyether.

Abstract: Described herein is cookware formed from a laminate, said laminate comprising three sheets made from a thermoplastic resin, the inside sheet made from a thermoplastic resin having a higher use temperature than the two outside sheets.

Abstract: This invention concerns a process for fabricating fiber reinforced thermoset resin articles. The process comprises the steps of (a) providing in a distributing zone, an intimate mixture of one or more fibers with a melting point or a glass transition temperature above about 130.degree. C. and a fiber length greater than about 0.5 centimeters, and a liquid resin, said resin having a viscosity of less than about 3000 centipoise at 25.degree. C., (b) injecting said mixture into the cavity of a closed matched metal die mold, thereby filling said cavity with said mixture, (c) heating said mixture so as to cause an exothermic reaction to occur in said mold, and (d) opening said mold and recovering a thermoset fiber reinforced molded article therefrom.

Abstract: There is disclosed a thermosetting phenolic resin composition, suitable for use in injection molding, which resin composition contains a molding grade phenolic resin and an effective amount of a reactive compound (e.g., para-t-butylphenol) that is capable of reducing the viscosity of molding compositions containing said phenolic resin compositon to a processable viscosity at a temperature at which the period of time within which said molding composition cures to a thermoset state is longer than the period of time that said molding composition is in the runner during a normal injection molding operation. There is also disclosed molding compositions containing said phenolic resin composition, and an injection molding process utilizing the same.
