Ethylene-styrene copolymers and phenol-triazole type complexes, catalysts, and processes for polymerizing

   
   

Metal-ligand complexes that are useful as precursors to catalysts for the polymerization of olefins are provided. Certain of the catalysts are particularly effective at polymerizing ethylene and styrene into copolymers having novel properties, including a low molecular weight and close comparison between vinyl and methyl end groups.

Se proporcionan los complejos del Metal-ligand que son útiles como precursores a los catalizadores para la polimerización de olefins. Seguro de los catalizadores sea particularmente eficaz en el etileno y el estireno de polimerización en los copolímeros que tienen características de la novela, incluyendo un peso molecular bajo y cierre la comparación entre el vinilo y los grupos metílicos del extremo.
