Abstract:
      An amphipathic polyurethane elastomer(APU) with the interpenetrating polymer network(IPN) was prepared by the solution polymerization using polyester urethane as hydrophobic component and light-cured polyglycol as hydrophibic component.The influence of the hydrophibic and hydrophobic components ratio，and the light curing condition on the mechanical properties of IPN type APU was investigated.The results showed that the optimum mechanical properties of IPN type APU were obtained if 0.010 part of light sensitive agent by mass in APU was used，APU was exposed to the light for 6 min and conditioned for 20 h before light exposure.
