Thermal transformations of copolymers based on poly(methyl methacrylate) and amino-containing compounds

The thermal transformations of copolymers based on PMMA and amino-containing compounds, such as amines, oxyamines, and diamines, were studied by IR spectroscopy, DTA, and TGA. It was established that the formation of cyclohexylmethacrylimide units in macromolecules favors an increase in the thermal stability of the copolymer based on PMMA and cyclohexylamine. The thermal stability of the copolymers based on PMMA and bifunctional ethylenediamine, hexamethylenediamine, and monoethanolamine is enhanced, primarily due to formation of N,N-alkylenebis(methacrylamide) and analogous amidoester groups.
