Optical recording of stable holographic grating in a low Tg statistical copolymer covalently functionalized with an azo-dye
A novel photoaddressable copolymer with low glass transition temperature was synthesised and its optical properties were studied. The photoresponsive material was obtained from chemical modification of a poly(styrene-co-acrylic acid) copolymer. A holographic polarization grating was recorded in the...

A novel photoaddressable copolymer with low glass transition temperature was synthesised and its optical properties were studied.

It is shown that the holographic grating stored in the material is highly stable in time, despite the fact that the polymer glass transition temperature is near room temperature.
