CA 2294580

Process for preparing amino functionalized diene polymers with 1,4-trans linkage content equal to or greater than 70%. The invention also concerns polymers of such type, a rubber composition and a tire casing containing those polymers. The process of preparation according to the invention comprises polymerizing at least one diene monomer by means of a lithium catalytic system, which comprises at least one hydrocarbon solvent, one compound A of a IIIA group metal, one compound B of an alkaline earth metal and one aminolithium initiator C. A rubber composition vulcanizable with sulfur according to the invention is such that it contains at least said polymer. A tire casing according to the invention is such that it contains said composition.

Procédé de préparation de polymères diéniques fonctionnalisés amine, et à teneur en enchaînements 1,4-trans qui est égale ou supérieure à 70 %. L'invention concerne également de tels polymères, une composition de caoutchouc et une enveloppe de pneumatique comportant ces polymères. Le procédé de préparation consiste à polymériser au moins un monomère diénique à l'aide d'un système catalytique lithié, lequel est constitué d'au moins un solvant hydrocarboné, d'un composé A d'un métal du groupe IIIA, d'un composé B d'un métal alcalino-terreux et d'un initiateur C amino-lithié. Une composition de caoutchouc vulcanisable au soufre selon l'invention est telle qu'elle comporte au moins ledit polymère. Une enveloppe de pneumatique selon l'invention est telle qu'elle comporte ladite composition.
