The polymerization and processing of polypropylene require rapid evaluation of its product performance, especially in catalyst and new product development, and there is an urgent need for fast and accurate characterization methods to shorten the research and development cycle. However, the existing characterization methods for polypropylene are seriously lagging behind in terms of process control and timely delivery requirements, and there is an urgent need to develop new characterization methods. Numerous studies have shown that near-infrared spectroscopy is an effective method for rapidly characterizing the properties of polypropylene [1–5].
