Abstract

Polymeric esters and amides were prepared from the imidazolids of poly(10-undecenoic acid), poly(10,11-epoxyundecanoic acid) and, poly(5,6-epoxyhexanoic acid). They include polymeric reaction products of 4-hydroxybisphenol, 4-cyano-4′-hydroxybisphenol, 4-aminobisphenol, cholesterol, and carbazole. The reactions were carried out via the imidazolids of the polyacids and gave yields between 75% to quantitative with conversions from 60-100%. Aromatic amines gave nearly quantitative conversion; for quantitative substitution with alcohols, their alkali salts should be used. The polymeric esters and amides were briefly studied for their thermal and mesogenic properties.
