Abstract
Thermal properties were studied of many compounds inhibiting the combustion of polymers-compounds with chloro- and bromo-substituted aromatic and cycloaliphatic fragments in the molecule. The ability of antipyrenes to undergo distillation and decomposition with the liberation of gaseous halogen-containing products during isothermal and dynamic heating in argon was determined both in the free state and in radation-modified binary and ternary (with addition of Sb 2O 3) mixtures with PE. It was found that the type of halogen and the chemical structure of antipyrene have a marked effect on the temperature range, type and rate of liberation of halogen in the form of hydrogen halide and antimony trihalide, which basically determines the fire-resistance of polymer materials containing these antipyrenes.
