Poly(N-acylurea)-clay nanocomposites consisting of a modified montmorillonite and poly(N-acylurea) were prepared from which poly(amide-imide)-clay nanocomposites were subsequently obtained via the sequential self-repetitive reaction of poly(N-acylurea). The moderate T(g) of poly(N-acylurea) allows the nonlinear optically active polymer to exhibit high poling efficiency; in situ poling and curing increased the T(g)s of poly(amide-imide)-clay nanocomposites. Electro-optical coefficients, r(33) of similar to 17-20 pm/V (830 nm), were achieved; high temporal stability (120 degrees C) and waveguide optical losses of 3.4-3.9 dB/cm at 1310 nm were also obtained for poly(amide-imide)-clay nanocomposites.
