Preparation and thermal behavior of the formulation of Ftorsam-39 with SKF-26(ONM) fluorine rubber


A synthetic procedure was designed to prepare formulations from Ftorsam-39 monomer (perfluoro-2,5-dimethyl-3,6-dioxanonoic acid triethoxysilylpropylamide) with SKF-26(ONM) fluorine rubber (poly(vinylidene fluoride-co-hexafluoropropylene)) in a presence of AGM-9 (γ-aminopropyltriethoxysilane) as a catalyst and co-reagent. The content of fluorine rubber in the compositions was varied from 10 to 54 wt.%. Thermal properties of the formulations obtained with the ratio Ftorsam-39: SKF-26(ONM): AGM-9 = 40: 54: 6 (wt.%) were assessed using thermomechanical and thermogravimetric analysis and differential scanning calorimetry.
