The structure-dependent mode of action and effectiveness of flame retardants on polymers and textiles is still unclear, since flame retardation is a very complex process that usually takes place transiently and varies depending on the location, in which transport processes and chemical processes are coupled in the condensed as well as in the gas phase. In order to better understand the fundamentals of the mode of action, on the one hand the influence of substituents on phosphorus-containing flame retardants on two important textile fibers (cotton and PET) is to be investigated in a cooperative project by systematically varying the flame retardants, and on the other hand a new generic experiment is to be set up and used that enables a stationary investigation of the gas phase with mass spectrometric methods. Here, the permeability of textiles by well-defined and temperature-controlled gas mixtures is exploited. In combination with the investigation of the residues as well as established - but less detailed - investigation methods of flame retardants, mechanistic insights into the mode of action of flame retardants in both phases are expected to be obtained, as well as insights into the influence of substituents on the effectiveness of flame retardancy.

阻燃剂对聚合物和纺织品的结构依赖性作用模式和有效性仍然不清楚，因为阻燃是一个非常复杂的过程，通常是瞬时发生的，并且根据位置而变化，其中运输过程和化学过程在冷凝和气相中耦合。为了更好地了解基本原理的作用方式，一方面研究了取代基对含磷阻燃剂对两种重要纺织纤维的影响（棉和PET）将在一个合作项目中通过系统地改变阻燃剂，另一方面，将建立和使用新的通用实验，其使得能够用质谱方法对气相进行固定研究。在这里，纺织品的渗透性明确和温度控制的气体混合物被利用。结合对残留物的调查以及已建立的但不太详细的阻燃剂调查方法，预计将获得对阻燃剂在两个阶段中的作用模式的机械见解，以及对取代基对阻燃效果的影响的见解。
