Abstract
IN recent months the importance of the reactivity of the free radicals in polymerization systems has been stressed, in particular the ability of a free radical both to initiate and terminate reaction chains1. The emphasis, however, has been on the ability of the radical in question to terminate the growing chains2, and it is the object of the present communication to direct attention to the lowered rate of initiation of growing chains which results from the use of certain catalysts.
