Liu, Qiaoyang published the artcilePreparation and UV -curing properties of oxazolidine-2-one based acrylates, Formula: C15H20O6, the publication is Polymers for Advanced Technologies (2022), 33(8), 2416-2424, database is CAplus.
Three oxazolidine-2-one based acrylates monomers were synthesized by the reaction of oxazolidine-2-one with 1,6-hexanediol diacrylate (HDDA), neopentyl glycol diacrylate (NPGDA) and trimethylolpropane triacrylate (TMPTA). The mol. structures of the products were characterized by FT-IR, 1H NMR and electrospray ionization high resolution mass spectrometry (ESI-HRMS). The photo-polymerization kinetics of the synthesized oxazolidine-2-one based acrylates were investigated by real-time IR spectroscopy. The results showed that the oxazolidine-2-one based acrylates with 1 weight% 2-isopropylthioxanthone (ITX) could be cured to form a transparent film under UV irradiation The UV curing speed of oxazolidine-2-one based acrylates with 1 weight% ITX was better than that of TMPTA with 1 weight% ITX and 3 weight% Et 4-(dimethylamino) benzoate (EDB) as co-initiator. Based on the HRMS anal. of oligomers extracted from the UV-cured film, the plausible photopolymerization mechanism was proposed. The synthesized monomer formula with CN996 resin can be 3D printed forming various models with smooth surface, good accuracy, excellent thermal stability and 99.4% gel content.
