Abstract

Abstract: 21 groups of peaks at high field and 11 groups of peaks at low field are assigned to individual carbon atoms in various diad environments, based on different compositions of butadiene-styrene copolymers, the empirical calculated values and consulted the data in the literatures. Some new points of view about the assignment have been put forward with the aid of ¹³C NMR spectra recorded on a superconducting NMR spectrometer.

Key words: butadiene-styrene copolymer, ¹³C NMR spectrum, sequence distribution
