The sensitivity of organometallic catalysts to oxygen, epoxy groups, amines, water or in general heteroatom functionalized substrates has often hampered their evolution from research laboratories to full-scale, on-line industrial processes. A new stable catalyst for ROMP reactions, able to overcome these drawbacks, has been synthetized. It rapidly polymerizes cyclic olefins in highly active environments and in very drastic condition of temperature, reactivity and viscosity. The new catalyst is stable up to 180°C in contact with oxirane rings and aromatic primary amines.

Abstract
The sensitivity of organometallic catalysts to oxygen, epoxy groups, amines, water or in general heteroatom functionalized substrates has often hampered their evolution from research laboratories to full-scale, on-line industrial processes. A new stable catalyst for ROMP reactions, able to overcome these drawbacks, has been synthetized. It rapidly polymerizes cyclic olefins in highly active environments and in very drastic condition of temperature, reactivity and viscosity. The new catalyst is stable up to 180°C in contact with oxirane rings and aromatic primary amines.File in questo prodotto:
