This document describes the analysis of epoxy resins using GPC viscometry with the Agilent 390-MDS Multi Detector Suite. GPC viscometry allows for accurate determination of molecular weight distribution of complex polymers, which influences physical characteristics such as curing time of epoxy resins.
The document details a method for analyzing epoxy resins, specifically focusing on determining the molecular weight distribution and structural properties of epoxide pre-polymers. It explains that accurate molecular weights are difficult to obtain due to the complex nature of these polymers but can be achieved using Gel Permeation Chromatography (GPC) viscometry.
It is used for multi-detector gel permeation chromatography (GPC) viscometry to analyze epoxide pre-polymers.
The analysis uses two Agilent PolarGel-L columns with dimensions of 300 x 7.5 mm.
The flow rate for the dimethyl formamide eluent is set to 1.0 mL/min.
