Abstract

Procédé de préparation de copolymères d'isobutylène contenant des insaturations et des atomes d'halogènes réactifs, caractérisé par le fait qu'il consiste à faire réagir un agent d'halogénation appartenant en particulier à la classe des halogènes et des hydracides halogénés avec des copolymères d'isobutylène et de triènes linéaires, les triènes linéaires étant présents en une quantité allant de 0,1 mole % à 8 moles % par rapport à l'isobutylène. Les copolymères de l'invention donnent des vulcanisats ayant des caractéristiques mécaniques et de résistance à la chaleur exceptionnelle et résistant à l'oxydation, pouvant être utilisés pour les pneus, courroies transporteuses, tubes de transport de fluides chauds, produits de scellement et d'étanchéité, etc.Process for the preparation of isobutylene copolymers containing unsaturations and reactive halogen atoms, characterized in that it consists in reacting a halogenating agent belonging in particular to the class of halogens and halogenated hydracids with copolymers linear isobutylene and trienes, the linear trienes being present in an amount ranging from 0.1 mole% to 8 mole% relative to isobutylene. The copolymers of the invention give vulcanizates having exceptional mechanical and heat resistance characteristics and resistant to oxidation, which can be used for tires, conveyor belts, tubes for transporting hot fluids, sealants and chemicals. sealing, etc.
