    摘要: The present invention relates to methods to improve the dampening characteristics of compositions and the improved compositions. The compositions made by the method comprises (a) a polymer system selected from the group consisting of immiscible polymer blends, miscible polymer blends, copolymers, thermoplastic polymers and thermosetting polymers, and (b) a block copolymer comprising: (i) at least one block derived from aromatic vinyl units and (ii) at least one block derived from at least isoprene and a vinyl aromatic monomer and optionally butadiene, and having a glass transition temperature of at least 10° C. In a preferred embodiment, the block copolymer comprises at least one block of polystyrene and at least one block derived from isoprene, styrene and butadiene, and the polymer system comprises at least one polyamide resin.

    摘要: This invention relates to data storage media, and more particularly to data storage media having both a data storage layer and an adjacent transparent overlayer wherein the data storage layer is capable of reflecting an energy field incident upon said transparent overlayer prior to being incident upon said data layer. Specifically, this invention relates to data storage media having thin transparent polyestercarbonate overlayers.
