eng Mesomorphic properties of new ferroelectric liquid crystals containing laterally substituted biphenyl benzoate core and chiral 2-alkoxypropionate unit Liquid crystalline compounds containing laterally substituted biphenyl benzoate core and chiral 2-alkoxypropionate unit were synthetised. Sequence of phases and phase transition temperatures were determined. Temperature dependences of spontaneous polarisation and complex permitivity were measured in polar phases with ferroelectric properties. Strong contribution of the Goldstone mode was estimated in the ferroelectric phase. Liquid crystals;ferroelectric properties;mesomorphic properties;spontaneous polarisation
