Published in 2019 at "Journal of Applied Polymer Science"

DOI: 10.1002/app.47876

Abstract: Polymer materials with different surface‐to‐volume ratios require different mechanisms of flame retardants regarding condensed phase and gas phase activity. The flame retardant formulations in poly(ethylene terephthalate) (PET) are investigated regarding a condensed phase and gas… read more here.

Published in 2018 at "ChemCatChem"

DOI: 10.1002/cctc.201801469

Abstract: A catalytic process to produce glycolide, the cyclic dimer of glycolic acid (GA), is proposed. Glycolide is the key building block of the biodegradable plastic polyglycolic acid. Instead of the current industrial two‐step route, which… read more here.
