Samoilenko, T., Iarova, N., Menzheres, H., Brovko, O. (2014). The Sensitization of Aliphatic Epoxy Photopolymerization in Epoxy-Acrylate Interpenetrating Polymer Networks. French-Ukrainian Journal of Chemistry, 2(1), 5–9. https://doi.org/10.17721/fujcV2I1P5-9

The paper discuses the phenomenon of the sensitization of the aliphatic epoxy photopolymerization in the presence of acrylate oligomers while forming epoxy-acrylate interpenetrating polymer networks. The photopolymerization process was studied by IR spectroscopy and the properties of the final products – by the Gardner test, crosshatch adhesion test, and the pencil hardness test. The epoxy groups conversion, which is rather low in aliphatic epoxy polymers, was found to alter with the increase of acrylate compounds content. The materials synthesized on the base of interpenetrating polymer networks were shown to reveal fine properties and may have a potential application as coatings.
