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.
