The relationship between sequence distributions and molecular weight distributions of S-SBR

obtained from styrene and butadiene anionic copolymerization at various conversions with THF/Li

as an initiator has been studied by

C-NMR

GPC. The results showed that the molecular weight distributions of the copolymer couldbe correlated sophisticatedly to the binary sequcne distributions or the monomer unit distributions of the copolymer in a corrected Poisson’s distribution from.
