INTRODUCTION

In the recent years an increased interest to chemistry and technology of perfluoro-olefin oxides was caused by their high reactivity and variety of oligomers and polymer materials produced on their base possessing unique physico-mechanical properties and exploitation characteristics which allowed to solve very different problems in nuclear power engineering, radioelectronics, space and aircraft technique and other newest branches of science and technique (1,2).

Such materials possess resistance to environmental unfavorable factors and aggressive chemicals with preservation of their own physico-chemical properties over a wide temperature range. Polymers based on tetrafluoro-ethylene oxide (TFEO) are of particular interest. Among them there are crystal polytetrafluoroethylene oxide surpassing traditional Teflon by a number of indices, fluororubbers with a glass transition temperature to minus 50-minus 80oC produced by co-polymerization of vinylidene fluoride and perfluoroalkylvinyl ethers on the basis of TFEO, membrane materials, lubricants, surfactants and many other substances produced from bifunctional fluoromonomers based on TFEO and difluoroanhydrides of perfluoro-dicarbonic acids (3-12).

This paper is an attempt to systematize data on TFEO properties available in literature and to draw attention of researchers to wide possibilities to create unique materials on its base.
