Олігоестери з функціональними діалкілпероксидними групами

Using the method of low temperature polycondensation of pyromellitic acid tetrachloroanhydride with polyethylene glycols and tert-butylperoxymethanol, oligoesters with functional dialkyl peroxy groups are synthesized. Their surface activity in the water solution and their thermal stability are researched. Методом низькотемпературної поліконденсації тетрахлорангідриду піромелітової кислоти з поліетиленгліколями і трет-бутилпероксиметанолом синтезовано нові олігоестери з первинно-третинними діалкілпероксидними функціональними групами.

Synthesis and Selfassambling of Amphiphilic Oligoesters Based on Pyromellitic Acid

The method for synthesis of a new class of amphiphilic oligoesters of pyromellitic acid is developed. As hydrophilic fragments polyethylene glycols or polyethylene glycol mono methyl ethers were used, as lipophilic ones – primary fatty alcohols or cholesterol. The structure of the synthesized oligoesters was confirmed by IR- and PMR-spectroscopy. The oligoesters could solubilize water-insoluble substances, for example such effective antitumor lipophilic drug as curcumin.
