Flame retardants are the chemicals that provide fire resistance to combustible materials. These compounds create a protective layer on the surface of a material, prevent burning and stop flame from spreading. Organophosphorus compounds are among broadly used flame retardants. Vinyl phosphonates and alkyl bisphosphonates are highly efficient as flame retardants; they can be easily synthesized as a result of catalytic reaction between alkynes and H-phosphonates. In its turn, electron microscopy proved to be an efficient tool for observing changes in the structure of treated and untreated materials after burning. More detail...
