Polybenzimidazole is well known for its thermal stability, chemical resistance, and excellent mechanical properties. Most resin monomers, which have been used in dental applications, need strong durability, small shrinkage, biocompatibility, and easy polymerization. Therefore, based on the properties of PBI, it is expected to overcome the problems of conventional dental restorative materials. In this study, poly[2,2’-(m-phenylene)-5,5’-bibenzimidazole] (PBI) was synthesized through condensation polymerization from isophthalic acid (IPA) and 3,3’-diaminobenzidine (DAB) in polyphosphoric acid (PPA) at 200℃ for 24 hours. In addition, diamine-terminated PBI oligomer was synthesized by adjusting the mol ratio between IPA and DAB. Photopolymerizable methacrylic-PBI oligomer (MA-PBI) was also prepared from diamine-PBI oligomer and methacrylic acid (MAA), and characterized by FT-IR, 1H-NMR and TGA. Ethoxylated bis-GMA (EBPDMA) was formulated with irgacure 819 as a photoinitiator, and photopolymerized by DLP 3D printer, then finally used to evaluate their compressive strength by universal testing machine (UTM).
