Abstract: A liquid or spreadable, vulcanisable rubber mixture based on a plurality of polymers, of which at least one is olefinically unsaturated, are prepared in such a manner that they can be cured by two different chemical reaction mechanisms which can be activated successively and can be catalysed at least substantially independently of one another. This is achieved by preparing a rubber mixture from - 30-70 parts by weight of a polymer A containing an average of at least 2 hydroxyl groups per macromolecule, - 70-30 parts by weight of a polymer B which is compatible with A and contains an average of at least 2 carboxylic acid and/or carboxylic anhydride groups or at least one carboxylic acid and one carboxylic anhydride group per molecule, - 10-120 parts by weight of vulcanisation assistants and if desired fillers and/or auxiliaries and - if desired 0.01-5 parts by weight of esterification catalysts, at least one of the polymers A and B being vulcanisable via its olefinic double bonds under conventional reaction conditions at elevated temperatures.
