A quantum chemical NMR study of branched and unbranched fluoropolymers

Аннотация

The work demonstrates the results of quantum chemical calculations of ¹⁹F and ¹³C NMR spectra of model fluorocarbon C_nF_2n+2 molecules with various configurations and hydrocarbon chain molecules. The possibilities to determine the chain length, formation of branches, identification of fluorine substitution for hydrogen during the fluorination of hydrocarbon paraffins and polymers are discussed.
