UV‐Cured Interpenetrating Acrylic‐Epoxy Polymer Networks: Preparation and Characterization

This is the authors' abstract. We don't add key points for this paper.

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. magnified image
