Synthesis of Polyurethane Acrylate with High Toughness and Its Application

In this study we synthesized a series of polyurethane acrylate(PUA) with high properties by selecting different polyols as the backbone of the polymer. Compared to the properties of polyurethane acrylates, the results show that the PUA with the backbone of polybutadi-enediol possess excellent toughness and good low - temperature flex resistance.
