Abstract

Copolymers obtained from radical styrene polymerization in the presence of poly(tetramethylene disulfide) were subjected to sulfur-sulfur bond cleavage by butyllithium. The resulting oligo-and poly (styrene) molecular weight distribution is identical with the sequence distribution of styrene sequences in the copolymer which proved to be a multiblock. From this, the apparent chain transfer constant of poly(tetramethylene disulfide) was calculated.
