Molecular weight determination of HTPB resins by vapor pressure osmometry (VPO) and gel permeation chromatography (GPC): The effect of calibration standards

摘要

GPC and VPO behaviours of HTPB samples have been examined in toluene employing polystyrene and polybutadiene standards. The results show that the molecular weights obtained depend on the nature of the calibration standards, particularly in the GPC analysis.
