    摘要: A process for coupling a living carbocationic polymer by reacting two molecules of a living carbocationic polymer with a coupling agent, the coupling agent having the formula I: CR1R2═CR3-Zn—CR4═CR5R6   (I) wherein R1, R2, R3, R4, R5 and R6 are, independently from one another, hydrogen, alkyl, or alkenyl, or two of R1, R2, R3, R4, R5 and R6, together are alkylene or alkenylene, Z is CR7R8, R7 and R8 are, independently from one another, hydrogen or alkyl, and n is 0 or an integer from 1 to 5, with the proviso that, when R3 is hydrogen, both R1 and R2 are different from hydrogen, and, when R4 is hydrogen, both R5 and R6 are different from hydrogen. The process allows for the convenient preparation of ABA-type block copolymers and of telechelic polymers.
