Reinforced plastics based on unsaturated-polyester resins. Determination of the residual styrene monomer content, as well as the content of other volatile aromatic hydrocarbons, by gas chromatography1 Scope This International Standard specifies a method for the determination, by gas chromatography, of the residual styrene monomer in reinforced plastics based on unsaturated polyester (UP) resins in the polymerized state. The residual styrene monomer content is an important criterion in evaluating the degree of cure of UP resins in the polymerized state. The method can also be used for the simultaneous determination of other volatile aromatic
