Several classes of cholesteric and photoreactive homo- and copolyesters were synthesized and characterized. Most of these polyesters were prepared in such a way that a chiral spacer (e.g. isosorbide) was polycondensed with a photoreactive dicarboxyli

A dicarboxylic acid which served as a mesogen in all poly(ester-imide)s was prepared from 4-aminocinnamic acid and trimellitic anhydride. The acid chloride of this monomer was polycondensed with various chiral diols derived from (S)-3-bromo-2-methyl-

A homopolyester was prepared from 4-carboxycinnamic acid and a diol derived from 4-mercaptophenol and (S)-3-bromo-2-methyl-1-propanol. With this spacer and a 1 :1 combination of 4-carboxycinnamic acid and naphthalene-2,6-dicarboxylic acid, copolyeste

Starting from commercial S- or R-3-bromo-2-methylpropanol, several new spacer diols were prepared. These spacers were polycondensed with the acid chloride of N-(4'-carboxyphenyl)trimellitimide. The poly(ester-imide)s derived from chiral, aliphatic sp

Various poly(esterimide)s of N-(4-carboxyphenyl)trimellitimide were prepared by transesterification of its dimethyl ester with various aliphatic diols. The following spacers were used: combinations of different α,ω-dihydroxyalkanes, mirtures of 1,1
