Thermotropic liquid crystalline polyarylates

Jackson and co-workers reported in 1976 [21,22] (on work carried out in 1971) that poly-p-oxybenzoyl-modified poly(ethylene terephthalate) was found to exhibit thermotropic liquid crystalline characteristics. A variety of thermotropic liquid crystalline polyarylates have since been described, and some of these also contain flexible spacer units [23-30].

I would like to acknowledge the numerous contributions of M.Okamoto,T.Yamanaka and N.Goto who prepared the thermotropic liquid crystalline polyarylates. 

Thermotropic liquid crystalline polymers containing 3-diketonato groups (-R-CO-CH2-CO-R) capable of metal ion binding (Cu , Ni ) in the main chain of polyesters or in the side chain of polyarylates are described [237]. Binding of at poly(ethyleneimine) and other polymers containing 1,2-diimino parts in the polymer chain were prepared for the use in chemotherapy of cancer [238].
