Modeling Free Radical Ethylene Polymerization with Multifunctional Comonomers in Tubular Reactors: Influence on Microstructural LDPE Properties



Summary: A kinetic model is developed to predict the effect of multi-functional comonomers in the high-pressure polymerization of ethylene in industrial tubular reactors. Two different modified acrylate based comonomers were tested in the simulation for their influence on molecular-weight distribution and branching densities. A comparison of both methods shows their potential to be used in an industrial process.
