Abstract—When combined with organoelement compounds of nontransition metals, quinones, which usually
act as inhibitors of radical processes, are capable of effective initiation of radical vinyl polymerization at a
rather low temperature and make it possible to control the lifetime of the polymer chain. The molecular mass
of the resulting polymers increases linearly with conversion, which provides indirect evidence that polymeriza-
tion proceeds according to the pseudo-living chain mechanism.
