    Influence of Organoboron Compounds on Ethylene Polymerization Using Cp2ZrCl2/MAO as Catalyst System by Luis Alexandro Valencia López, Francisco Javier Enríquez-Medrano, Ricardo Mendoza Carrizales, Florentino Soriano Corral, Adali Castañeda Facio, Ramón Enrique Díaz de León Gómez

    Published 2014-01-01
    “…Organoboron compounds of nonionic and ionic nature, tris(pentafluorophenyl)borane, and N,N-dimethylanilinium tetra(pentafluorophenyl)borate were evaluated to act in conjunction with MAO as activators on ethylene polymerization by using the catalyst Cp2ZrCl2. A decrease on the catalytic activity was observed in both cases in relation with a reference polyethylene which was synthesized in absence of any organoboron compound. …”
