Adhesives / sealants based on liquid rubbers

There will be described temperature-curing reactive compositions based on natural and / or synthetic olefinic double bond-containing elastomers and vulcanizing agents, at least one liquid polyene having a molecular weight from 400 to 80,000 and at least one liquid polybutadiene having a narrow molecular weight distribution and a microstructure of 10 to 20% vinylic 1,2 double bonds, 50 to 60% trans 1,4-contain double bonds and 25 to 35% cis-1,4 double bonds in the molecule. Furthermore, these compositions contain a vulcanizing system of sulfur and accelerators and / or, if appropriate, quinone oximes. These compositions are suitable for use as one-component adhesive, sealant, or coating compound in automobile having high tensile shear strengths and high impact peel strength, particularly at low temperatures.
