The possibility of evaluating with acceptable accuracy the composition of a two-polymer mixture that is well separated by gel-permeation chromatography was studied by using mixtures of high-molecular-weight polybutadiene (m, = 4.5 x 105) and low-molecular-weight polyisobutylene (i@, ca, 10~). It was
## Abstract A procedure is presented for determining the concentration of polymer lithium, alkyllithium, and monomer by use of smallβmolecule GPC. The system poly(styryllithium), butyllithium, styrene, and benzene are used to illustrate the method. The method as presented has a lower limit on the d
