摘要：
The characterization of molecular weight distribution, intrinsic viscosity and polymer chain branching as a function of molecular weight for polymer standards and polymers of commercial interest are reported for tetrahydrofuran (THF), dimethylformamide (DMF) and dimethylacetamide (DMAC) mobile phases. The instrument used in this study is a single capillary GPC - Viscometer/Data Analysis System. In this chapter additional studies on operational variables, particularly dead volume, is reported. The validity of universal calibration in DMF and DMAC is discussed for a range of polymer types, and column packings.
