DOI: 10.1002/app.45816
Abstract: A precisely sequenced ethylene–propylene (EP) fully alternating copolymer was synthesized via trans-1,4-polymerization of isoprene catalyzed by Ziegler–Natta catalyst followed by hydrogenation. This EP copolymer was used as model polymer for studying structure–property relationship. An ethylene–propylene… read more here.
