摘要: Abstract For the first time new type of liquid single crystal elastomers forming chiral smectic A * (SmA ) phase has been prepared using lactic acid derivative as a co-monomer. The synthesis and basic characterization ferroelectric crystalline co-monomer based on differential scanning calorimetry small/wide-angle X-ray scattering are reported discussed. monomer possesses paraelectric SmA SmC phases over broad temperature range. preparation together with their mesomorphic structural properties is also reported. New possess orthogonal 50 K
