Abstract
  • This paper reports the assignments of the 13C NMR resonances of the Sbb and Sag methylenes observed in the spectra of copolymers of propylene with trace amounts of enriched ethylene-1-13C. The assignment is achieved by comparing the chemical shifts calculated by an empirical method (at the CH2 stereochemical pseudoexad level), with the experimental spectra of regioregular copolymers with different stereochemical structure. The implications of the observed Sbb and Sag resonances on the stereochemical polymerization mechanism are also discussed. (literal)
