This paper deals with the changes on switching fields and response times of
a PDLC system when small percentages of the thermoplastic polymer are repl
aced by the same quantity of monomer. An improving of the electro-optical p
roperties, i.e. a reduction in driving voltages and rise times, is obtained
when about 10 weight % of polymer is replaced by monomers with a high solu
bility in liquid crystal droplets. Morphology changes are observed for subs
titutions larger than 20 weight %.
