Gives a method of determining the residual styrene monomer content in reinforced plastics based on unsaturated polyester resins in the polymerized state by gas chromatography. The residual styrene monomer content is an important criterion in evaluating the degree of cure of UP resins in the polymerized state. Not applicable to UP resins of high chemical resistance. Covers references, determination with Wijs' solution and test report.
