Abstract
Polymerizations of (R,S)‐3,7‐dimethyl‐1‐octene in the presence of heterogeneous or homogeneous isotactic specific catalysts give very similar products with a homopolymeric isotactic structure. The insertion of (R,S)‐3,7‐dimethyl‐1‐octene into the metal‐CH~3~ bond (both heterogeneous and homogeneous catalysts) is highly stereospecific and stereoselective.
