Abstract :
Spectroscopic absorption measurements in the wavelength range from 700 to 300 nm are used to study the orientation of optically nonlinear side-chain groups in an acrylic polymer and dye guest molecules in a polymer matrix by a corona poling process. The time stability and the annealing behavior of these films are measured. The poling process produces efficient orientational order at room temperature of the acrylic side-chain polymers. With stepwise annealing up to poling conditions the orientation order was measured. The guest-host systems show a different behavior
