    • 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.
    • 通过使活性碳阳离子聚合物的两分子与偶联剂反应来偶联活性碳阳离子聚合物的方法,具有式I的偶联剂:<?in-line-formula description =“In-line Formulas”end =“lead” ?>>>>> 2 2>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> 其中R 1是一个或多个,其中R 1,R 2,R 3,R 6, R 2,R 3,R 4,R 5,R 5和R 6, 氢,烷基或链烯基,或R 1,R 2,R 3,R 3,R 3, R 4,R 5和R 6一起是亚烷基或亚烯基,Z是CR 7 R 7, R 8,R 7和R 8彼此独立地为氢或烷基,n为0或1至5的整数, 条件是当R 3是氢时,R 1和R 2都不同于氢,并且wh R 4是氢,R 5和R 6都不同于氢。 该方法可以方便地制备ABA型嵌段共聚物和遥爪聚合物。
