México Photochemical cross-linking studies at different temperatures (room temperature, Tg and maximum exothermal of crosslinking peak) are shown for three series of polymers containing diacetylene-groups in the main chain and polar chromophores derived from benzene, azo- and di-azobenzene, as pendant groups.
We establish the optimal irradiation time and temperature that permit them being poled and cross-linked with minimal dye-degradation.
The degradation process was followed by a diminution of the respective maximum absorption peak.
These conditions could extend the mean life-time of the second order nonlin...
