Fluoroalkyl end-capped N-(1,1-dimethyl-3-oxobutyl)acrylamide oligomer [RF-(DOBAA)n-RF] in silica nanocomposite can exhibit a nonflammability characteristic even after calcination at 800 °C, through the formation of ammonium hexafluor osilicate corresponding to −154.8 p.p.m. signal in 19 F MAS NMR spectra during the nanocomposite reactions; in contrast, no formation of ammonium hexafluorosilicate during the composite reaction affords a usually flammable behavior for RF-(DOBAA)n-RF oligomer in silica nanocomposite.
