Summary
The title polymers were prepared as potential non-linear optical materials with a degree of substitution 3–13 mole %. During UV-irradiation and/or heating near the glass transition temperature these polymers crosslink through the hydrazone groups and their UV-vis absorption band diminishes. Degrees of crosslinking of swollen samples were estimated. A possibility of simultaneous crosslinking and poling of these polymers is discussed.
