| Abstract: | Summary The cationic copolymerization of isobutene (I) and trans-1,3,5-hexatriene (HT) at low temperature occurs randomly (rI=0.59, rHT=1.57). The prevalent 1,6-opening of the triconjugated system of HT was ascertained mainly by 1H- and 13C-NMR analysis. The formation of gelled products was avoided by working in a homogeneous medium and the cyclization of the triene units by copolymerizing I and HT in bulk. |
