Several preparation procedures of oligomeric alkylhydroquinone terephthalates containing four and more benzene rings, from 2-alkylhydroquinones, terephthaloyl chloride and monofunctional acid chlorides as well as 4-methoxyphenol are described. Oligoesters containing four to seven benzene rings were prepared in multi-step reactions of the defined compounds, whereas oligoesters containing more than seven benzene rings were obtained by a two-step polycondensation of an excess of alkylhydroquinones with terephthaloyl chloride followed by the final reaction of the obtained polycondensation products terminated by hydroxyl groups with anisoyl chloride. The phase transition temperatures and the chemical compositions of the compounds studied are given.
