Pyrolysis-gas chromatography-mass spectrometry for studying N-vinyl-2-pyrrolidone-co-vinyl acetate copolymers and their dissolution behaviour

► SEC and Py-GC-MS for characterization of PVP-VA copolymers. ► Quantitative Py-GC-MS of copolymers to calculate monomer ratios. ► Py-GC-MS for dissolution behaviour of PVP-VA copolymers in water. ► SEC combined with Py-GC-MS to provide copolymer composition as function of molecular weight.
