A novel route for producing soluble polyacetylene–polyisoprene block copolymers
Abstract
A novel cobalt catalyst system for the synthesis of soluble polyacetylene–polyisoprene block copolymers, via the anionic to Ziegler–Natta route is reported; preliminary experiments indicate that this catalyst is less susceptible to impurities and more versatile than the polymeric titanium catalyst route reported previously.
