Abstract
A process is described for flame-proofing organic polymeric materials by means of a low temperature plasma treatment in the presence of at least one volatile, low-molecular compound. The process comprises subjecting a volatile compound, selected from a halogen-free phosphorus compound, to the low temperature plasma, such that a homogeneous polymeric structure forms on the organic material. A very wide range of organic materials can be effectively flame-proofed with the process of this invention without adversely affecting their other properties such as mechanical properties or photochemical stability.
