G. Scherowsky et al., FERROELECTRIC LIQUID-CRYSTALLINE SIDE-GROUP POLYMERS DERIVED FROM MESOGENIC VINYL ETHER MONOMERS, Liquid crystals, 19(5), 1995, pp. 621-627
Two classes of ferroelectric polymers, polysiloxanes and polyvinyl eth
ers, have been synthesized, starting from the same mesogenic vinyl eth
er as precursor. The polysiloxane materials obtained by polymer analog
ous reaction of vinyl ethers with H-siloxanes exhibit larger ranges of
ferroelectric S-C phases than the corresponding polyvinyl ethers. Th
e effect of changing the nature of the link of the terminal chiral end
group on the phase behaviour and ferroelectric properties of the new
side chain polymers is reported.
