From the state of the art and our own preliminary work it is clear that a large number of patented methods exist for the production of step index and gradient index profile fibers. However, the fact that these production processes are either discontinuous (pulling processes from predefined cylinders) is a considerable time (gel polymerization and in-line polymerization in the extrusion of POFs) due to polymerization still to be carried out Production speed is limited (dry spinning process). To solve this problem the project partners developed a continuous and scalable melt spinning process for the production of gradient index profile fibers. Although the basic suitability of the technology has been demonstrated by the previous preparatory work, considerable improvements have to be made on the one hand and on the other hand on the control of the refractive index profiles in order to be able to use this new process in a targeted and controlled manner to become. For this purpose, a better understanding of the structure formation process of the optical polymer during filament formation is necessary.

从现有技术和我们自己的前期工作来看，显然存在大量用于生产阶跃折射率和梯度折射率分布光纤的专利方法。然而，事实上，这些生产过程要么是不连续的（从预定圆筒中的拉出过程），要么是相当长的时间（凝胶聚合和POF挤出中的在线聚合），因为聚合仍然要进行，生产速度有限（干纺过程）。为了解决这个问题，项目合作伙伴开发了一种连续且可扩展的熔体纺丝工艺，用于生产梯度折射率异形纤维。尽管之前的准备工作已经证明了该技术的基本适用性，但一方面必须在折射率分布的控制上做出相当大的改进，以便能够以有针对性和受控的方式使用这种新工艺。为此，有必要更好地了解光学聚合物在长丝形成过程中的结构形成过程。
