    • The invention relates to a process for chemical marking and identification of information in polymers and additives, such as ageing additives, thermal stabilizer additives, light stabilizer additives, plasticizer additives or flame retardant additives and dyes and other high-value additives. The marking is effected by the use of defined atomic masses in the form of isotopes of suitable elements in chemical compounds which are incorporated into the polymer matrix and anchored during the production. The result is a chemical code which can be recalled over the entire product life without adversely affecting the properties of the polymer through high concentrations of extraneous substances. It is possible by this process to trace back the origin of a polymer, to detect possible mixtures with chemically identical products from other manufacturers, or to clarify at a later stage whether an additive has been added in the concentration specified.
    • 本发明涉及用于化学鉴定和识别聚合物和添加剂中的信息的方法,例如老化,热保护,防晒剂,增塑剂或阻燃添加剂和染料以及其他高质量添加剂。 通过使用化学化合物中合适元素的同位素形式的限定的原子质量来进行标记,所述化合物在生产过程中并入和锚定在聚合物基质中。 其结果是一种化学编码,可以在聚合物的整个产品寿命期间使用,而不会通过高水平的异物影响聚合物的性能。 通过这种方法,可以追踪聚合物的来源,从其他制造商那里检测与化学成分相同的产品的可能混合物,或者在事后澄清添加剂是否已添加到指定浓度。
