Modeling and Simulation in Polymer Reaction Engineering (eBook)

Klaus-Dieter Hungenberg has been Vice President Polymer Reaction Engineering at BASF SE until his retirement in 2013. In 2012 he received an Honorary Professorship at the University of Paderborn. He is (co-)author of more than 100 scientific articles and patents. Michael Wulkow founded the company Computing in Technology (CiT) in 1992 and since then has been involved in projects, research and numerous publications on the modeling and numerical treatment of processes in technical chemistry, biology, particle technology and pharmacokinetics.
