Paper Abstract

The Electro-Optical (EO) effect has been studied in three different sidechain polymers (Tg: 140, 174 and 200$DEGC) both during poling and after poling. At the end of the poling process, when the poling field is switched off, a significant quasi-instantaneous decrease of the EO effect is observed, which--in our opinion--is indicative for motional hindrance during poling. The three polymers differ mainly in the flexibility of the coupling between the DANS- like sidechains and the backbone. A stronger coupling results in more hindered polability, but also in a higher Tg and better high temperature stability of the sidechain orientation. The role of hydrogen bonding is also discussed.
