The thermochromism as a reversible temperature dependency of the color of polymer-based materials has not been researched in depth, yet. By now, it is not understood in detail how temperature variation affects color changes in complex polymer systems. Color became an important quality criterion in plastics processing. With the aim to decrease the amount of speck-off materials by time-saving measurement techniques color measurement systems are adapted close to the production line. Thus, evaluation of color at elevated temperatures is a great challenge dealing with thermochromic phenomena attending the entire production chain. For determining thermally-induced color transitions in polymer-compounds extensive studies of commonly used polymer-compounds regarding to molecular and structural properties and molecular interaction between different components must be carried out. Models describing thermally-induced color transitions of polymer-compounds need to be developed and validated in order to improve predictability and evaluation of color characteristics based on VIS- spectroscopic measurement techniques.

热致变色作为聚合物基材料颜色的可逆温度依赖性，尚未得到深入研究。到目前为止，还没有详细了解温度变化如何影响复杂聚合物系统的颜色变化。颜色已成为塑料加工中的重要质量标准。为了通过节省时间的测量技术减少斑点材料的数量，颜色测量系统被适配为靠近生产线。因此，在高温下评估颜色是一个巨大的挑战，涉及整个生产链的热致变色现象。为了确定聚合物化合物中的热致颜色转变，必须对常用的聚合物化合物进行关于分子和结构性质以及不同组分之间的分子相互作用的广泛研究。描述聚合物-化合物的热致颜色转变的模型需要被开发和验证，以提高基于维斯-光谱测量技术的颜色特性的可预测性和评估。
