The polymerizations of styrene initiated by 2,2′-azobisisobutyronitrile have been carried out in the presence of various organic hydroperoxides, such as 1,1-dimethylethyl (<B>I</B><SUB><B>a</B></SUB>), 1,1-dimethylbutyl (I<SUB><B>b</B></SUB>), and 1-methyl-1-phenyl-ethyl hydroperoxides (<B>I</B><SUB>c</SUB>) at 60 °C. The polymerization rate increased with the concentration of <B>I</B><SUB><B>c</B></SUB>, but became rather retarded with that of <B>I</B><SUB><B>a</B></SUB> and <B>I</B><SUB><B>b</B></SUB>. This phenomenon can be explained by the difference in the radical induced decomposition for the hydroperoxides. The hydroperoxide (<B>I</B><SUB><B>c</B></SUB>) decomposes with a radical displacement on the peroxide bond; however, <B>I</B><SUB><B>a</B></SUB>, and <B>I</B><SUB><B>b</B></SUB>, in addition to this reaction, decompose with the radical hydrogen abstraction of the hydroperoxyl group. The peroxyl radical formed (ROO·) subsequently gave rise to a primary radical termination.
