Oxidation of thiocarbonylthio end groups in polymers made by radical polymerisation in presence of thiocarbonylthio agents, involves treatment with ozone-containing gas in order to stabilise the polymer |
摘要 |
A method for the partial or complete oxidation of one or more thiocarbonylthio end groups of a polymer obtained by radical polymerisation controlled by reversible addition-fragmentation with the aid of thiocarbonylthio reagents, involves contacting the polymer with ozone-containing gas so that the ozone reacts with the thiocarbonylthio groups. An independent claim is also included for polymers obtained by this method. |
