Реферат: The investigations were based on mixtures of perfluoroalkenes produced by electron-beam irradiation of PTFE wastes. Results concerning perfluorohept-1-en showed that the terminal perfluoroalkenes react preferably with dinucleophilic reactants to form non-saturated ether and amid structures. Reactions of perfluoroalkene mixtures with nucleophilic reactants (dioles, diamines) lead to crosslinking. Primary addition products of terminal perfluoroalkenes hydrolyze with amines or phenols/alcohols to carbonyl compounds and form allylic structures. Internal perfluoroalkenes of the mixture and allylic products, respectively, add the nucleophilic compound and rearrange partially into stable vinylic products. Mixed ether-ester structures and non-saturated polyamides, respectively, are formed. The dinucleophilic reactant determines essential properties of the fluorine compound. Thermally and chemically induced substitution leads to highly crosslinked structures opening new areas for fluorocarbons.
