Abstract:
The present invention relates to a composition and process for enhancing the controlled radical polymerization in the presence of nitroxyls and nitroxylethers by adding a chain transfer agent selected from the group consisting of mercaptanes, thioethers and disulfides to the polymerizable mixture. A further subject of the invention is the use of mercaptanes, thioethers and disulfides for increasing rate and yield of controlled radical polymerizations in the presence of a nitroxyl or a nitroxylether.
