13C NMR analysis of propylene‐butylene copolymers by a reaction probability model

13C NMR analysis of propylene‐butylene copolymers by a reaction probability model 13C NMR spectra of propylene‐1‐butene copolymers have been studied at 90.55 MHz. At this high field, many lines previously not resolvable were found to be sensitive to comonomer sequence distribution; these microstructures have been fully assigned. Each NMR spectrum was analyzed by a reaction probability model. Information available includes polymer composition, comonomer sequence distribution, and Markovian reaction probabilities. The use of this model reduces errors in the determination of sequence distribution and furthermore enables the product r1r2 of the reactivity ratios to be determined for the copolymer/catalyst system. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Polymer Science Part A Polymer Chemistry Wiley

Abstract

13C NMR spectra of propylene‐1‐butene copolymers have been studied at 90.55 MHz. At this high field, many lines previously not resolvable were found to be sensitive to comonomer sequence distribution; these microstructures have been fully assigned. Each NMR spectrum was analyzed by a reaction probability model. Information available includes polymer composition, comonomer sequence distribution, and Markovian reaction probabilities. The use of this model reduces errors in the determination of sequence distribution and furthermore enables the product r1r2 of the reactivity ratios to be determined for the copolymer/catalyst system.
