Title: | The determination of the gases released during heating of a flame retardant for polymers - Coupling of TG with FTIR, MS and GC-MS | Authors: | MULLENS, Jules REGGERS, Guy RUYSEN, Marleen CARLEER, Robert YPERMAN, Jan FRANCO, Dirk VAN POUCKE, Lucien |
Issue Date: | 1997 | Publisher: | JOHN WILEY & SONS LTD | Source: | JOURNAL OF THERMAL ANALYSIS, 49(2). p. 1061-1067 | Abstract: | The oxidative degradation of HET-acid (1,4,5,6,7,7-hexachlorobicyclo [2.2.1] hept-5-en-2,3-dicarboxylic acid) is studied by the combination of TG, FTIR, MS and GC-MS. The gases evolved during the decomposition of this flame retardant are investigated on-line by FTIR and by MS. Simultaneously the evolved gases are collected by an adsorbent and, after the thermal experiment, desorbed to release the volatile products for identification using GC-MS. The combination of these techniques offers the unambiguous identification of the evolved products as a function of temperature. The main identified products are CO2, H2O, Cl-2, HCl, C2Cl4, maleic acid anhydride, HET-acid anhydride, chlorinated cyclic hydrocarbons and chlorinated unsaturated linear hydrocarbons. | Notes: | Mullens, J, LIMBURGS UNIV CTR,DEPT SBG,B-3590 DIEPENBEEK,BELGIUM. | Keywords: | EGA; flame retardant; HET-acid; polymer | Document URI: | http://hdl.handle.net/1942/3285 | ISI #: | A1997XJ18300056 | Type: | Journal Contribution |
