Several polyarylates based on bisbenzylidenoketones have been synthesi
zed by interfacial polycondensation, Two distinct types of polymers ha
ve been obtained: guest-host systems and polyarylates with NLO (nonlin
ear optical) side chains. The dispersion of the linear refractive inde
x (no) is measured over the wavelength range from 800 to 2000 nm, The
Boling formula, based on a semiclassical model of a simple harmonic os
cillator, is used to calculate the NLO susceptibility X-(3).
