The synthesis and characterization of a novel epoxy‐based photocrosslinkable nonlinear optical (NLO) polymer exhibiting enhanced thermal stability is reported. The synthesized polymers show spectroscopic properties (NMR, IR, UV) in accordance with the proposed structures. A glass transition temperature (Tg) of 112°C and a thermal degradation temperature (Td) of 310°C were recorded. The poled polymer film exhibits stable second‐order nonlinear optical activity (d33 = 19.5 pm/V) over a period of 500 h as characterized by the temporal response of the second harmonic signal at room temperature. © 1996 John Wiley & Sons, Inc.
