The role of electron pair donors in the carbocationic polymerizations of isobutylene is still debated. Here, the copolymerization of isobutylene and alloocimene initiated by trimethyl pentyl chloride/TiCl4 in hexane(s)/MeCl (60/40 v/v) solvent system at −80 °C with di‐tert‐butylpyridine as a proton trap displays the rapid monomer consumption phenomenon in the absence of dimethyl acetamide. In contrast, the copolymerization is living in the presence of dimethyl acetamide.
