Abstract: The kinetics of MDF-2-based oxidative thermal destruction of polyester methacrylate has been studied. The effective energy of activation calculated by oxygen absorption in the interval from 160 t o 200°C amounts t o 24.1 kcal mole^-1. Analysis of the destruction products seems to indicate that oxygen initiates the process by interacting first of all with — CH₂— groups that are in the α-position t o the ester methacryl group. A new effective inhibitor of the thermal and oxidative destruction of three-dimensional polyester methacrylates, poly-2-methyl-5-ethynyl-pyridine, has been found.
