摘要

<正> A new type of liquid crystalline polyesters with resorcin as one part of the mesogenic unitconnected together by polymethylene

or phenylene group

and lateral groups consisting of arigid azobenzene as another part of the mesogenic unit were synthesized by interfacialpolymerization of diacyl chlorides in 1

2-dichloroethane and 2

4-dihydroxy-4’-nitroazobenzen inaqueous alkaline solution. The polyester structures were confirmed by proton NMR and IRspectra. Their phase transition behavior and texture were studied by polarizing microscopy andDSC.
