They promise to concentrate efficient fire retardancy at the key position between pyrolysis zone and gas phase. Examples of residue/char forming and intumescent materials are used to illustrate the influence of mass and heat barrier effects on the fire behavior of materials and general results are presented. A comprehensive understanding of the mechanisms and structure-property relationships in fire retardancy is presented.

For glass fiber reinforced PA-66, P4 promotes char formation in the condensed phase. Barrier effects and the reduction of combustible volatiles were identified as fire retardancy mechanisms. For HIPS, P4 acts in the gas phase, mainly trapping radicals. The heat release per mass loss polymer is reduced due to an incomplete combustion.

So far, mostly timeconsuming (micro) infrared or micro-Raman spectroscopic methods are applied. Here an faster alternative Approach is presented based on a Raman processspectrometer with fiber-optical probes in combination with multivariate data analysis. T2 - 12.
