✦ Synopsis

Dielectric absorption and dispersion has been observed in two adducts of p-toluenesulphenyl chloride (TSCI to eis-l.4-polybutadiene (PBD) viz. the 100') o and 50°0 adducts respectively (mole ratios of TSC to monomer of 1 : 1 and 1:2). In the 100°o adduct, measurements at 1 kHz over the temperature range -54 to +85 showed :(, /3 and 7 relaxations. The behaviour of the :t-relaxation in the 50% adduct, when compared with the 100°o. is interpreted in terms of a block structure for the less heavily modified polymer.

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.
