Overview
Researchers at the University of Maryland, College Park, have invented methods and a catalyst for the cyclopolymerization of non-conjugated dienes.The catalyst is an amindinate-based zirconium precatalyst. Upon activation with a borate co-catalyst, it not only allows for the stereospecific living polymerization of alpha-olefins, but can provide for the cyclopolymerization of non-conjugated dienes. In living polymers, the "polymeric molecules ‘live’ for an indefinite period of time", and "the living ends are potentially able to grow" so long as a monomer remains available.
The catalyst and method provide access to new classes of polyolefin block co-polymers that can be separated and ordered. Given the enormous range of alpha-olefins and non-conjugated dienes that are readily available, the results suggest that a new line of polyolefin materials with tunable properties may now be at hand.
A large chemical manufacturer is reviewing the activity of the catalysts.
