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, 1 H‐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 Ca 2+ 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
