摘要: Abstract In this study a new method (LP-FTIR) was introduced to promote the better understanding of polymer degradation, as well effect flame-retardant additives. The technique is based on FTIR analysis gaseous products which originate from laser induced decomposition in specific combustion cell. situ degradation products, produced by pyrolysing various samples and flame-retarded composites (in air or inert atmosphere) at different power (0.1–10 W), allows their identification quantification without loss any component. Ethylene-vinyl acetate copolymer (EVA) polypropylene (PP) were used model substrate for setting parameters investigation dependence results reproducibility atmosphere. has been utilized determining EVA/Al(OH)3/melamine borate composites, also characterized coupled cone calorimeter technique. order chemical changes solid phase LP-FTIR combined with ATR-IR spectroscopy. Based results, conventional (cone calorimeter-FTIR) compared.
