Application of Pyrolytic Chromatography-Mass Spectrometry in Quality Control of Building Polymers and Composites

In a brief review, the possibilities of the pyrolytic gas chromatography-mass spectrometry (Py–GC–MS) method in the identification and quality control of polymers and composites based on them used in building materials, in determining the thermal and physical characteristics of high-molecular compounds, their molecular mass distribution, in establishing the structure of the structural units of homo- and heteropolymers, in the identification of additives used in polymer materials, in quality control and safety of polymer products. Pyrolytic cells used in Py–GC–MS allow the suspended sample (both solid and liquid) to be placed in a quartz-coated steel crucible, which can be heated up to 1050^оC. Modern Py–GC–MS complexes operate in 6 main modes: analysis in the pyrolysis temperature programming mode; single-stage pyrolysis; thermal desorption; two-stage and multi-stage analysis with chromatographic separation of each thermal zone; and reaction pyrolysis. Examples of the use of the Py–GC–MS method in quality control of polyvinyl chloride, composite materials based on polyethylene, wood-composite materials, fluorocarbon elastomers, compositions of polyurea and polyurethane, inorganic binders are given.
