METHOD FOR PARTIAL OR TOTAL OXIDATION OF ONE OR SEVERAL THIOCARBONYLTHIO ENDS OF A POLYMER OBTAINED BY RADICAL POLYMERISATION CONTROLLED BY REVERSIBLE ADDITION-CLEAVAGE

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 comprises a step of contacting said polymer with an ozone-containing gas, during which ozone reacts with the one or several thiocarbonylthio ends. The invention also relates to the polymer obtainable by the aforementioned method and uses thereof.
