Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Syntheses of eight novel methacrylates bearing phosphonic acid groups were synthesized in three to five steps. The interaction of these monomers with hydroxyapatite was investigated using ¹³C‐NMR spectroscopy. Free radical homopolymerizations were carried out in a mixture ethanol/water (2.5/1, v/v) using 2, 2′azo(2‐methylpropionamidine) dihydrochloride as initiator. The copolymerization of these monomers with a mixture HEMA/GDMA (5/3, mol/mol) was investigated by photo‐DSC. Dentin shear bond strength measurements showed that 2‐methacryloyloxy‐3‐(1, 1, 2, 2‐tetrafluoroethoxy)propylphosphonic acid <bold>4b</bold>, 2, 3‐dimethacryloyloxypropylphosphonic acid <bold>18</bold> and 3‐(methacryloyloxy)‐2, 2‐(di[(dihydroxyphosphoryl)methyl])propyl methacrylate <bold>23</bold> are promising candidates for dental adhesives. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg26mrz92j" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
