Transition temperature control of liquid crystalline poly(heptene sulphone)s

SummaryLiquid crystalline poly(heptene sulphone)s containing cholesteryl undecylenic ester and cholestanyl undecylenic ester were synthesized. The polymers displayed cholesteric mesophases during thermal transition. The clearing temperatures were from 114 to 172°C depending on the molar ratio of mes...

Summary:SummaryLiquid crystalline poly(heptene sulphone)s containing cholesteryl undecylenic ester and cholestanyl undecylenic ester were synthesized. The polymers displayed cholesteric mesophases during thermal transition. The clearing temperatures were from 114 to 172°C depending on the molar ratio of mesogenic esters in the polymers.
