Abstract. Sequence distributions of the 1-butene comonomers in ethylene-1-butene copolymers were determined by analyzing the 13C NMR spectra using an optimization calculation technique. The proposed method takes the possible errors in NMR measurements into account. Applying the method to the spectra of some linear low density polyethylenes with 1-butene as the comonomer gave physically reasonable values of triad comonomer distribution. The method was thought to be useful by giving the possible maximum and minimum triad concentrations reflecting the chain structures. We also tried to use the method for determination of larger sequence structures over triad distribution.
