摘要：

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