Received Date: 30 August 1994

A series of novel mesogenic polyesters with 2-dich1oromethylhydroquinone moieties weresynthesized by polycondensation of the novel diacyl chloride monomer 2-dichloromethyl-1, 4-bis (4'-chloroformylbenzoyl) oxybenzene-(I) with α,ω-polymethylenediols including ethyleneglycol, 1, 4-butanediol, 1, 6-hexanediol and 1, 10-decanediol. The diacyl chloride monomerwas synthesized by simultaneous transformations of both the carboxy and formaldehydegroups of 2-formyl-1, 4-bis (4'-carboxybenzoyl) oxybenzene into acyl choride and dichloromethyl groups respectively.The syntheses of the monomer (I) and the polymers were reported.
