FLUORINATED POLYMERS AND PROCESS FOR PREPARATION THEREOF

摘要

FIELD: chemistry of polymers. SUBSTANCE: fluorinated polymers having thermoplastic elastomeric properties containing in the macromolecule perfluoropolyoxyalkylene sequences of general formula: -CFO-(CFCFO)-(CFO)-CF- wherein m/n is 0.2-5, are prepared by polycondensation of respective condensable perfluoropolyoxyalkylene alkylene monomers represented by general formula (I) which are rendered functional by respective reactive groups and have functionality of at least 1.97, preferably at least 1.99. These polymers have average molecular weight by 50%, preferably by 100% greater than average molecular weight of the respective polymers prepared from perfluoropolyoxyalkylenes of general formula (I) and having functionality of not greater than 1.56. EFFECT: improved properties of the fluorinated polymers.
