The free radical polymerization of styrene initiated by 1,l ,2,2-tetraphenyl-l,2-diphenoxyethane (TPPA) can be described as a kind of dead end polymerization. At the beginning of the polymerization, mainly oligomers are formed by primary radical chain termination. These oligomers can be characterize

✦ Synopsis
The rate of the free radical polymerization of styrene with substituted ethanes as initiators is characterized by a competition of "normal" and primary radical termination. With decreasing initiator concentration the reaction order with respect to monomer and initiator changes in favour of a normal termination. The kinetics of this polymerization process is derived and compared with experimental results.
