Abstract

By alternating the supply of propylene and ethylene monomers, alternating polypropylene and polyethylene films were produced on one model Ziegler-Natta catalyst. This way, we could show that the active polymerization sites remain under the growing polymer films and thus the monomer molecules must transport through the growing polymer to the active sites.
