The present invention is directed to a method for preparation of polyolefins containing exo-olefin chain ends. The method involves quenching a cationic quasi-living polyolefin polymer system with a nitrogen-containing five- membered aromatic ring having at least two hydrocarbyl substituent compounds attached to the ring.
La présente invention concerne un procédé de fabrication de polyoléfines avec terminaisons de chaîne exo-oléfiniques. Ce procédé consiste à éteindre un système polymère cationique polyoléfinique quasi-vivant avec des composés à noyau aromatique à cinq éléments contenant de l'azote, noyau auquel sont attachés au moins deux composés hydrorcarbyle de substitution.
