Obtainment and thermal characteristics of the composition of perfluoro-2,5-dimethyl-3,6-dioxanonanoic acid triethoxysilylpropylamide (Fluorosam-39) and fluororubber SKF-32

Abstract

A new methodology for obtainment of compositions based on Fluorosam-39 monomer (triethoxysilylpropylamide perfluoro-2,5-dimethyl-3,6-dioxanonanoic acid) with fluororubber SKF-32 (vinylidene fluoride with trifluorochloroethylene co-polymer) in the presence of AMEO (γaminopropyltriethoxysilane) as a catalyst and co-reactant was developed. Content of fluororubber in compositions varied from 10 to 55% (mass.). Thermal properties of the composition, obtained from Fluorosam-39:SKF-32:AMEO at the ratio 45,5: 48,5: 6 (mass.%) were measured using thermomechanical and thermogravimetric analysis methods.
