A series of side-chain liquid-crystalline polymers has been synthesised fro
m monomeric oxetanes, The synthesis and liquid crystal properties of the mo
nomers and the polymers are discussed and it is shown that a short spacer u
nit can be used to obtain polymers with a flexible backbone which give broa
d liquid crystalline phases and low glass transition temperatures, Various
initiators were used for the polymerisation but the photoinitiator "SARCAT
KI 85(TM)", a disulfonium salt, yielded the best results.
