PERFLUORODIOXOLS, METHOD OF PREPARING THEREOF (VARIANTS), PERFLUORODIOXOLE HOMOPOLYMERS AND COPOLYMERS, THERMALLY PROCESSIBLE TETRAFLUOROETHYLENE COPOLYMERS |
摘要 |
FIELD: chemical industry. SUBSTANCE: described are new perfluorodioxols of formula I wherein R<SB>F</SB> is perfluoroalkyl having from 1 to 5 carbon atoms and X<SB>1</SB> and X<SB>2</SB> are the same and different from each other and are F or CF<SB>3</SB>. EFFECT: new class of perfluorodioxoles makes it possible to prepare homopolymers having superior mechanical properties and good thermal stability, are suitable for coating of electric cable by extrusion from melt. Also described is method of preparing compounds of formula I, perfluorodioxole homopolymers and copolymers and thermally processible tetrafluoroethylene copolymers. More efficient preparation method. 17 cl, 16 ex, 1 tbl
