Abstract:Polybenzoxazines are a type of thermosetting resin with good thermal resistance. A flame-retardant and degradable polybenzoxazine (ERY-a) was synthesized by a special bisphenol containing a bridging diacetal structure (ERY) and aniline. A systematic comparative study was conducted between ERY-a and bisphenol A/aniline-type benzoxazine (BA-a). Their chemical structures were confirmed by Fourier transform infrared (FTIR) spectra and nuclear magnetic resonance (NMR) spectra. The curing behaviors and polymerizatio… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
