“Since my child goes to the daycare, there is no craft lesson without hot glue. I do not want to miss hot glue especially for making lanterns."

Dr. Angela Heykamp is working as team leader for the C4 research & development department in Marl. Her main tasks include the investigation of alternative raw materials and the optimization of the feedstock quality for the C4-Verbund. Another challenge that Angela faces is the process optimization of the raffinate plant as well as developing and testing new catalysts.


Butene-1 is mainly used as co-monomer for polyethylene (LLDPE, HDPE) or co-monomer for ethylene/propylene copolymers where it improves for example the tear strength of the polymer. Further it is used as intermediate for the production of various products, for example antioxidants, plasticizers, herbicides, corrosion inhibitors or additives to lubricating and hydraulic oils.
