Structural investigations on low‐molecular‐weight polyisobutenes

Abstract
Structural investigations of low‐molecular‐weight polyisobutenes synthesized by selective polymerization and of commercial polyisobutenes were made by 1H‐ and 13C‐NMR spectroscopy. It is possible to attribute the signals to “normal” and to some unusual olefinic structures. A comparison was made to literature data.
