Abrégé
(EN)
This invention relates to a novel curing method of oligomers, using metal triflates, and particularly to the curing of hydroxyl terminated elastomers to achieve crosslinked polymers. The method finds particular use as an alternative cure methodology to replace isocyanate curing. There is further provided a cured and crosslinked polymer binder, which is particularly suitable and compatible for use with energetic materials.
(FR)
La présente invention concerne un nouveau procédé de cuisson d'oligomères au moyen de triflates métalliques, et en particulier la cuisson d'élastomères terminés par un hydroxyle, en vue d'obtenir des polymères réticulés. Ce procédé est particulièrement utile en tant que méthodologie de cuisson de rechange pour remplacer la cuisson isocyanate. L'invention concerne en outre un liant polymère cuit et réticulé, qui est particulièrement adapté et compatible pour être utilisé avec des matières énergétiques.
