## 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
Gel permeation chromatography produces a type of differential molecular weight distribution directly and rapidly. Conversion of these data to conventional molecular weight distributions and plots of distributions is time-consuming. A computer program is described to perform these operations readily.
Manual preparation of polymer samples for molecular weight characterization by solution methods such as gel permeation chromatography (GPC) is a timeconsuming, labor-intensive, and redundant task. Preparation of samples for high-temperature GPC characterization further complicates the procedure. A t
