ABSTRACT:
Dental resin systems prepared from polyfunctional or monofunctional highly-fluorinated methacrylate prepolymers are described. Preferred systems comprise (a) a major amount of a polyfluorinated aligomeric polyfunctional methacrylate such as (PFMA), preferably in combination with a diluent monomer such as 1,10-decamethylene dimethacrylate (DMDMA), methyl methacrylate (MMA), neopentyl dimethacrylate (NPDMA), 1,6-hexamethylene dimethacrylate (HMDMA), etc., or mixtures thereof; and (b) a minor amount of a polyfluorinated monofunctional methacrylate (PFMMA), such as 1,1-dihydropentadecafluorooctyl methacrylate (PDFOMA) as a minor or secondary diluent monomer in a non-hydroxylated bis-GMA resin system. The products are generally useful as hydrophobic dental materials, esepcially as composited (with fillers), sealants and cements.
