✦ Synopsis

Acrylic groups containing phosphonic acids were synthesised by ether formation of ethyl achloromethylacrylate with hydroxyalkylphosphonates and subsequent hydrolysis to the corresponding phosphonic acid a-methyl-substituted acrylates. The structure of the synthesised monomers was confirmed by elemental analysis, IR, 1 H NMR, 13 C NMR and 31 P NMR spectroscopy. The monomers are stable in aqueous ethanol. The radical polymerisation of the monoacrylates in tetrahydrofuran with 2,29-azobisisobutyronitrile (AIBN) results in soluble polymers, whereas a phosphonic acid diacrylate results in a cross-linked polymer.
