Abstract

Thumbnail image of graphical abstract

Acrylic-epoxy interpenetrating polymer networks were prepared by means of UV curing. The photopolymerization process was investigated via real-time FTIR spectroscopy. The hybrid, cured films showed a broad tan δ peak in DMTA demonstrating the high damping properties of the hybrid, cured formulations. A decrease on shrinkage was achieved by increasing the epoxy-resin content in the photocurable formulation, with a consequent increase in adhesion properties.
