Abstract

Thermotropic liquid crystalline polyarylate(TLCP) is an essential type of thermotropic liquid crystal polymers which exhibit excellent mechanical properties

good thermal stability

stable dielectric properties and flexibility in processing. With the advent of information age and ever-growing demand for green chemistry

TLCP will occupy an increasingly broad market. From the perspective of polymer synthesis

structure and performances

engineering applications

this review summarizes the recent research progress of TLCP. To begin

the TLCP synthesis methods are described. From the standpoint of molecular design

the primary optimization solutions are described in detail in relation to the disadvantages of TLCP during processing

such as high melt temperature and high melt viscosity. Second

some commercialized TLCPs are introduced

further both the film and fiber variants of TLCP processing are covered. Finally

the main application areas of TLCP are briefly discussed.
