Abstract
Three ferroelectric copolysiloxanes with different molar mass have bee n synthesized. Mechanical measurements and electro-optical switching b ehaviour in both cell and thin film geometry are reported. Removal of short chains doubled (M) over bar(n) and slowed down electro-optical s witching but the mechanical properties were not affected. A further tw ofold increase in (M) over bar(n) by chain extension did not affect el ectro-optical switching times but improved the mechanical properties m arkedly.
