Abstract:	In this study, polymerizable phosphonate adhesives synthesized from Diethylchloro-phosphate and 2-Hydroxyethylmethylacrylate and formulated with G-methacryloxy-propyltrimethoxy silane is used in Bis-GMA/TEGDMA monomer system. All the raw materials and finished products are characterized with infrared spectra, vapor pressure osmometry, viscosity and gel test. The bonding strength to tooth materials is determined by Instron machine. The work emphasizes applying polymeric organic phosphonate adhesive to Bis-GMA/TEGDMA monomer system and investigates the appropriate conditions for the crosslinking of Bis-GMA/TEGDMA monomer system. Average bonding strength of 744 psi to enamel and 600 to dentine are obtained in comparision to 550 psi to enamel for phosphonate/silane/MMA/PMMA and 120 psi for the commercial product "Gluma".
