  • Patent number: 7960474
    Abstract: A single-component high-temperature-curing reactive composition based on natural and/or synthetic elastomers having olefinic double bonds and on vulcanizing agents is provided. Such compositions contain at least one liquid polyene with a molecular weight between 400 and 80,000, preferably between 800 and 25,000; at least one block copolymer with at least one polyene block and at least one saturated block; and a vulcanizing system of sulfur and accelerators and/or quinone oximes, if applicable. Such high-temperature-curing reactive compositions are useful as single-component adhesives, sealant or coating compositions or sealing compounds in automobile body manufacture.
    Type: Grant

  • Patent number: 7902298
    Abstract: High-temperature-curing reactive compositions based on natural and/or synthetic elastomers containing olefinic double bonds, and on vulcanizing agents, are described, which contain at least one liquid polyene having a molecular weight between 400 and 80,000 and at least one liquid polybutadiene having a narrow molecular weight distribution and a microstructure of 10 to 20% vinyl-1,2 double bonds, 50 to 60% trans-1,4 double bonds, and 25 to 35% cis-1,4 double bonds in the molecule. These compositions furthermore contain a vulcanizing system of sulfur and accelerators and/or, if applicable, quinone oximes. These compositions are suitable for use as a single-component adhesive, sealant, or coating compound in automobile manufacture, with high tensile shear strength and high impact peel strength even, in particular, at low temperatures.
