A study of copolymerization of 1-hexene with 2,5-norbornadiene using metallocene catalysts
Copolymerization of 1-hexene with a symmetrical diene, namely 2,5-norbornadiene was studied using four different metallocene catalysts. Copolymerization was found to occur exclusively through one of the two equally reactive endocyclic double bonds with ...
