Abstract
Manufacturing process for vulcanized elastomers, characterized in that one or more functional liquid diene prepolymers, having a degree of functionality of between 1.8 and 2.0, are present alone or in combination with one or more compounds chosen from the group consisting of bifunctional non-diene polymers, non-functional liquid polymers, small molecular weight bifunctional molecules, and containing, intimately mixed, the reinforcing fillers and vulcanizing or crosslinking agents usual for vulcanizing tire tires, with a bifunctional hydrocarbon chain extender compound in an amount such that in the mixture achieved the ratio of the number of the reactive groups of the hydrocarbon chain extender compound to the number of the reactive groups of the previous liquid functional polymers is equal to 1, and because this mixture is carried, in a first phase, at the temperature sufficient to exclusively obtain an elongation reaction of the hydrocarbon chain of the previous polymer and, in a second phase, at a higher temperature to perform crosslinking or vulcanization of the reaction product formed at the end of the first phase.
