N. Moszner et al., Monomers for adhesive polymers, 2. Synthesis and radical polymerisation ofhydrolytically stable acrylic phosphonic acids, MACRO CH P, 200(5), 1999, pp. 1062-1067
Acrylic groups containing phosphonic acids were synthesised by ether format
ion of ethyl alpha-chloromethylacrylate with hydroxyalkylphosphonates and s
ubsequent hydrolysis to the corresponding phosphonic acid alpha-methyl-subs
tituted acrylates. The structure of the synthesised monomers was confirmed
by elemental analysis, IR,H-1 NMR,C-13 NMR and P-31 NMR spectroscopy. The m
onomers are stable in aqueous ethanol. The radical polymerisation of the mo
noacrylates in tetrahydrofuran with 2,2'-azobisisobutyronitrile (AIBN) resu
lts in soluble polymers, whereas a phosphonic acid diacrylate results in a
cross-linked polymer.
