    摘要: A data storage medium includes a substrate, a reflective metal layer, and a haze-prevention layer between the substrate and the reflective metal layer. The substrate includes an amorphous thermoplastic resin having a heat distortion temperature of at least about 140° C., a density less than 1.7 grams per milliliter, and an organic volatiles content less than 1,000 parts per million measured according to ASTM D4526. The haze-prevention layer includes a material having a volume resistivity of at least 1×10−4 ohm-centimeters and a tensile modulus of at least about 3×105 pounds per square inch. The data storage medium resists hazing of the reflective layer at elevated temperatures.

    摘要: A method is provided for upgrading rock in the form of aggregate, block, shaped stone or concrete structures involving the treatment of such rock with a dilute aqueous solution of polyelectrolyte. Enhanced degradation resistance is achieved by further wetting the polyelectrolyte treated rock with a multi-valent ion metallic salt solution. Treated aggregate, portland cement and bituminous concrete compositions containing such treated aggregate are also provided.
