Abstract: In this paper a series of new thermoplastic liquid crystalline elastomers were synthesized by high temperature solution polycondensation of 4,4'-(terephthaloyldioxy) dibenzoyl chloride, 1,10-decandiol, and poly(ethylene glycol) (PEG 1500). Their thermal properties and liquid crystalline behavior were characterized by DSC and polarizing optical microscope. Tensile strength values of these block copolymers were in the range of 10~40 MPa, elastic modulus values 5~30 MPa, and elongation values at break 200%~320%.

Key words: Poly(ester-ether), Liquid crystalline elastomers, Thermal properties, Mechanical properties
