Title:
可逆的付加-フラグメント化により制御されるラジカル重合により得られるポリマーの1個または数個のチオカルボニルチオ末端を一部または完全に酸化する方法
Document Type and Number:
Japanese Patent JP2007509216
Kind Code:
A
Abstract:
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.
