The influence of physical crosslinks on the thermalproperties and photoinduced anisotropy in epoxy linear polymers with azobenzeneand alkyl side groups has been studied. Linear epoxy-based polymers were synthesized byreaction between diglycidyl ether of bisphenol A (DGEBA), Disperse Orange-3(DO3) and dodecylamine (DA).Isothermal annealing at different temperaturesproduced tail-to-tail association of DA alkyl chains that produced changes inglass transition temperature and optical response.
