- Summary
- A high-speed gel permeation chromatography (HSGPC) method was developed for the molecular weight parameter analysis of Estane as a minor component in LX-14 PBX formulations. Molecular parameters for Estane, so obtained, permitted the evaluation of various aging and accelerated aging treatments on the LX-14 samples. Parameters evaluated were: Number average molecular weight anti M/sub n/, weight average molecular weight, anti M/sub w/, and peak molecular weight, M/sub p/, as well as the derived ratio, anti M/sub w//anti M/sub n/, generally referred to as the molecular weight distribution index (MWD). The method employed the Waters high-speed gel permeation chromatograph (HSGPC) together with a Waters Model 440 uv detonator. Molecular weight data obtained had a standard deviation of approximately 5 percent.
