Abstract

A BTDA-based dimethacrylate monomer was synthesized via reaction of 3, 3′, 4, 4′-Benzophenone tetracarboxylic dianhydride (BTDA) and 2-Hydroxyethyl methacrylate (HEMA).The reactions were followed using FTIR spectroscopy and the product was characterized and confirmed using FTIR, 1H-NMR, and Elemental Analysis. The effects of temperature and pyridine as catalyst were investigated. The water contact angle on the surface of cured BTDMA and Bis-GMA-based resins were also measured and compared. FTIR studies showed an interaction between carboxylic acid groups of BTDMA and Ca2+ ions of CaO. The interaction of the resin with hydroxyapatite and tooth ash was also investigated. The interaction was also studied using thermogravimetric analysis (TGA). © 2002 Wiley Periodicals, Inc. J Appl Polym Sci 86: 3246-3249, 2002
