As a part of our effort to synthesize biopolymers from a completely renewable material source (di-linoleic diol), novel techniques of polymerization are used, e.g., Reversible Radical Recombination Polymerization (R3P). Besides methods of polymerization, analytical techniques are also being constantly developed. Recently, IR spectroscopy was successfully used to continuously monitor the process of chromatographic monomer purification. The resulting chromatogram simultaneously shows the time dependence and the wavenumber dependence of IR absorbances.

Poly(styrene-isobutylene-styrene) block copolymer (SIBS) is a very versatile material. Due to its excellent biocompatibility, it can be applied safely even in the human body. Now the areas of biomedical applications were extended even further: it can also be used for filtering purposes, e.g., as a porous membrane acting as an active layer of a COVID mask.

Abstract: This paper presents a new method for the amine-functionalization of poly(ethylene glycol) (PEG) of Mn =2050 g/mol via Candida antarctica lipase B (CALB)-catalyzed esterification of tert-butyloxycarbonyl (tBOC)-protected β-Alanine and L-Alanine. NMR showed full conversion for protected β-Alanine, and MALDI-ToF demonstrated the purity of the product. After deprotection, the desired diamine-functionalized PEG was obtained.
