This is a product usage manual for analyzing polyester polyols with gel permeation chromatography using the Agilent PLgel MIXED-E column.
This document details the analysis of polyester polyols, which are alcohols containing multiple hydroxyl groups used as reactants to make polymers such as polyester polyol. These polyols are formed by condensation or step-growth polymerization and are reacted with polyisocyanates to manufacture polyurethanes for rigid-foam and flame-retardant building boards.
The analysis is performed using gel permeation chromatography (GPC) with Agilent PLgel 3 pm MIXED-E columns. These columns are ideal for low molecular weight samples containing oligomeric fractions as well as polymers up to 30,000 MW. The document provides specific conditions for a separation demonstration, including the use of THF as an eluent and a flow rate of 1.0 mL/min.
