✦ Synopsis

Analysis of the CH--S and CH--CI multiplets in the t3C NMR spectra of modified polymers indicates that the addition of benzenesulphenyl chloride to cis-l,4-polybutadiene is not wholly random.

The analysis of the methylene resonances was inconclusive because of peak overlap and other uncertainties. The conclusion that the partially saturated polymers have some blocky character is in general agreement with earlier results on the physical properties of the adducts and on the kinetic ~ or th:addition reaction.
