摘要：
Urethane-urea copolymers with different main-chain structures have been synthesized, and their nonlinear optical (NLO) properties compared. The glass transition temperatures (T-g) depended on their main-chain structures. The optimum poling temperature of each copolymer was 45 degrees C higher than its T-g, indicating the existence of forces preventing the disordering of poled NLO groups. The observed temporal behavior of d(33) at 100 degrees C indicates that introducing urea groups into a polyurethane main chain can increase the temporal stability of the polyurethane without improving the stiffness of the main chain.
