Transition Metal Catalysts for Olefin Polymerization

Transition Metal Catalysts for Olefin Polymerization Princeton Docket # 14-3038 Presently, only free radical copolymerizations of ethylene and polar industrial monomers (e.g, vinyl acetate or acrylic acid) at high temperatures and very high pressures have been commercialized. This existing technology, however, inherently lacks precise control over...
