Copolymerizations of ethylene with endo ‐dicyclopentadiene (DCP) were performed by using Cp 2 ZrCl 2 (Cp = Cyclopentadienyl), Et(Ind) 2 ZrCl 2 (Ind = Indenyl), and Ph 2 C(Cp)(Flu)ZrCl 2 (Flu = Fluorenyl) combined with MAO as cocatalyst. Among these three metallocenes, Et(Ind) 2 ZrCl 2 showed the highest catalyst performance for the copolymerization. From 1 H‐NMR analysis, it was found that DCP was copolymerized through enchainment of norbornene rings. The copolymer was then epoxidated by reacting with m ‐chloroperbenzoic acid. 13 C‐NMR spectrum of the resulting copolymer indicated the quantitative conversion of olefinic to epoxy groups. © 1999 John Wiley & Sons, Inc.
