The synthesis and optical properties of a series of amorphous polyesters with amino-sulfone azobenzene chromophores in the main chain are presented. The condensation of alkyl diacid chlorides with 4-[(2-hydroxyethyl)ethylamino]-4Ј-(2-hydroxyethylsulfonyl)azobenzene ( 7) gave polymers that showed low
The relaxation of holographic phase gratings was examined to obtain some information about the involved photochemically induced changes. The studies were performed with statistical liquidcrystalline side group copolymers having different concentrations of the azobenzene dye. The formation of mesopha
## Abstract Poly(urethane acylsemicarbazide)s were synthesized with a two‐step process: (1) the __in situ__ generation of diisocyanate through the thermal decomposition of an azobenzene‐containing precursor diazide and a reaction with ester/ether polyols to form an isocyanate‐terminated prepolymer
