摘要: Abstract Thermal degradation processes in poly(monobenzyl itaconate), poly(mono-2-phenylethyl itaconate) and poly(mono-3-phenyl-1-propyl have been studied by DSC, TGA, EGA FTIR. These analyses indicated the absence of glass transitions three polymers occurrence thermal degradative at temperatures 120 δC. This behaviour is confirmed thermogravimetric (TGA) which allows us to distinguish between least different below 250 Evolved gas (EGA), employing an FTIR detector, infrared spectra residue allow speculate about reaction mechanisms. Three main reactions proposed °C, namely cyclic linear anhydride formation, with loss water corresponding alcohol, decarboxylation higher temperatures.
