Polymerization of olefins through heterogeneous catalysis. XVIII. A kinetic explanation for unusual effects

摘要: The development of a detailed kinetic model describing some the unusual effects observed in catalyzed olefin polymerization is presented. Based on method moments, describes rate hydrogen and comonomers, as well ability certain systems to incorporate long chain branches via internal and/or terminal double bond polymerization. Examples are provided demonstrating model's predict rates degrees with ethylene, propylene, 1-hexene monomers. In case multiple insertion mechanisms modeled compared experimental sequence length end group data. other examples used simulate an oscillating metallocene catalyst capable branch addition © 1997 John Wiley & Sons, Inc.
