surface activity

The polymer materials, which contain Phosphorus in the main chain, have considerable interest as materials for medical and biomedical applications. Therefore, it is actually to find a convenient method for obtaining polyetherphosphates. The article is discussing the method of obtaining polyethylene glycol ethylphosphate, which is a monomer for the preparation of polyphosphates. Polyethylene glycol ethylphosphate was obtained by interaction between a polyethylene glycol trityl ether and ethyldichlorophosphate.

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.

This article is devoted to quaternization of dimethylaminoethanol with various esters of ω-bromo carboxylic acids with subsequent acylation with maleic anhydride or with methacryloyl chloride led to formation of novel cationic surface active monomers. Синтезовано катіоноактивні мономери ряду малеїнатів та метакрилатів, які містять у молекулі фрагменти N,N-диметиламіноетанолу, кватернізованого естерами ω-бромо- карбонових кислот. Одержані сполуки є типовими поверхнево-активними речовинами, водні розчини яких знижують поверхневий натяг на межі водний розчин-повітря. 

The interaction of ε-caprolactone with methacrylic acid has resulted in formation of 6-methacryloylhexanoate which was subsequently converted into the corresponding chloroanhydride via the reaction with phosphorus trichloride. The reaction of chloroanhydride with poly(ethylene glycol) or poly(ethylene glycol) monomethyl ether yielded the corresponding surface active methacrylate monomers. During interaction of the hydroxyl group of poly(ethylene glycol) containing the monomer with the excess of phosphoryl chloride phosphate-containing monomer was synthesized.
