Determination of Styrene Monomer in Polyester Resins by Gas-Liquid Chromatography

摘要

Styrene, as well as other unsaturated monomers, are employed as cross-linking agents for unsaturated polyesters resins, and a suitable method of analysis for styrene is needed. Gas liquid chromatography (GLC) was used to determine styrene monomer without interference from other cross-linking compounds. A simple, solvent separation was utilized to separate the resin prior to the GLC analysis. The GLC separation was conducted on a Triton X-305 column with methyl isobutyl ketone used as the internal standard. (Author)
