The cationic polymerizations of 1,3‐pentadiene initiated by AlCl 3 in n‐hexane at 30°C have been carried out in the presence of various arenes, i.e. , benzene, toluene, p‐xylene, o‐ xylene, m ‐xylene and mesitylene. The presence of all these arenes have reduced in different degrees the formation of crosslinked products. Namely, the crosslinking reaction, a major side‐reaction during the cationic polymerization of 1,3‐pentadiene, has been suppressed by adding the aromatic compounds. The results showed that a chain transfer to arene took place and this transfer process hindered the generation of the crosslinked polymer. IR and 1 H NMR spectra have confirmed the existence of the corresponding aryl groups in the resulting polymers.
