    Abstract: Disclosed is a method for preparing saturated polyester used in various molded products, such as films, synthetic fibers, vessels and housings. In particular, the method improves mechanical properties, including tensile strength or impact resistance, of saturated polyester. In DMT method or TPA method, the saturated polyester is synthesized through transesterification or esterification and polycondensation, in which metal compounds, such as metal acetate compounds, metal hydroxides, and metal oxides, are added in the larger amounts upon synthesis, and thus crystalline internal grains are formed, thereby improving the mechanical properties. As such, the metal compound can be used alone or in combination with a phosphorous-based compound.

  • Patent number: 6403220
    Abstract: Novel phosphorus element-containing crosslinking agents for epoxy resin compositions based on an isomeric mixture of tris(2-hydroxyphenyl)-phosphine oxide compounds. Epoxy resins cured or crosslinked with the crosslinking agents of this invention yield non-halogenated, ignition resistant epoxy resin formulations. The ignition resistant epoxy resin formulations are advantageously used for making laminates for printed wiring boards and composite materials.

  • Patent number: 6399684
    Abstract: The present invention relates to polyamide/polymer blends having a morphology enhancing reagent selected from a phosphorous containing compound such as a hypophosphite salt. Significant physical effects are seen in Tensile strength as well as Vicat softening points. The blends having polyamide and a polymer selected from, for example, a neutralized ethylene copolymer, and the phosphorous containing reagent are useful in producing molded parts and other fabricated parts requiring high strength and toughness. Molded parts produced from such blends also have high gloss, high abrasion/scratch resistance and good high temperature properties.
