Abstract

Conformational analysis of two alternating copolymers, poly (ethylene imine-alt-ethylene oxide)(PEIEO) and poly (N-methylethylene imine-alt-ethylene oxide)(PMEIEO), has been carried out by the inversional-rotational isomeric state (IRIS) analysis of ab initio molecular orbital (MO) calculations and 1H and 13C NMR experiments for their model compounds. On the basis of the conformational energies derived therefrom and molecular mechanics and ...
