Abstract:

The structure of polymer products has obvious multi-level and polydispersity. The performance is also very rich. In this article, it was suggested that the rational design based on quantitative relationship between structure and performance and the precise manufacturing of product structures should be taken as the core research content and innovative development approach of the polymer product engineering. In order to accurately describe the relationship between polymer structure and performance, the database construction of polymer and polymer informatics derived therefrom, especially the application of artificial intelligence technology, should be paid more attention in the future. For more precise manufacturing of polymer structures, in the future, attention should be paid to the CNC manufacturing of molecules in the polymerization process. At the same time, the soft measurement technology for polymerization process should be continuously innovated and developed to improve the scope, accuracy and speed of the online detection of structure during the manufacturing process of polymer products. The article also pointed out that attention should be paid to the in-situ alloying and compounding methods of polymers in the reactor and the application research of reactive extrusion on molecular modification, group conversion, chain extension, cross-linking, alloying and compounding of polymers, so as to fully leverage their advantages in the precise manufacturing of multiphase and multi-component polymer products.

摘要：

聚合物产品结构具有明显的多层次性和多分散性，产品的性能也非常丰富。本文提出，应当把产品结构与性能间量化关系的构建，以及在此基础上进行的产品结构的理性设计与精准制造，作为聚合物产品工程的核心研究内容与创新开发途径；为更精确地描述聚合物结构与性能间的关系，未来应重视聚合物数据库建设及由此衍生的聚合物信息学，注重人工智能技术的应用；为更精准地进行聚合物结构的制造，未来应重视聚合物产品生产过程中分子的数控制造；同时，要不断创新发展软测量技术，提升聚合物制造过程中产品结构在线检测的广度、精度和速度。文章还指出，要注重聚合物的反应器内原位合金化、复合化方法，以及反应挤出在聚合物分子修饰、基团转换、扩链、交联以及合金化、复合化等方面的应用研究，充分发挥它们在多相多组分聚合物产品精准制造中的优势。
