Ternary Reactions among Polymer Substrate-Organohalogen-Antimony Oxides under Pyrolytic, Oxidative and Flaming Conditions

摘要

The objectives of the flame retardant chemistry study into the ternary reactions which occur among polymer substrates, organohalogen compounds and antimony oxides in the condensed phase under pyrolytic and combustion conditions were to elucidate in detail the principal solid state reactions which result in the formation of volatile antimony containing species and the role of the polymer substrate in the reactions; to establish a mechanistic basis for the role of the metal species in the degradation reactions which have been observed in the solid state; to relate the results from small scale degradation studies to the combustion behavior measured in the cone calorimeter and to attempt to establish useful parameters between the observed solid state chemistry and the combustion behavior.
