WebSep 1, 2024 · A phthalonitrile oligomer containing thioether bonds was successfully prepared via nucleophilic substitution reaction. •. The melting point of the oligomer is 86 ℃. •. Their curing kinetics and thermal properties of the cured polymers were demonstrated. •. The prepared polymers show excellent thermal properties. WebAmino acids involved in thioether bonds are labeled in blue or red. HPLC analysis of incubation of AlbA with (b) SboA8-27 and (c) SboA27-6 at T0 and after 120 min (UV detection at 215 nm). AlbA (20 µM) was incubated under anaerobic and reducing conditions in the presence of SAM (1 mM), peptide substrate (1 mM) and sodium dithionite (2 mM).
