| 摘要 |
The present invention relates to a method for partial or total oxidation of one or several thiocarbonylthio ends of a polymer, obtained by radical polymerisation controlled by reversible addition-cleavage with thiocarbonylthio agents, Said method comprising the step of contacting said polymer with an ozone-containing gas, during which ozone reacts with the one or several thiocarbonylthio ends. |
