Abstract

The polyolefins are the most widely used synthetic resin and greatly influence nearly every walks of life. About 70% polyolefin production is made from the immobilized polyolefin catalysts in gas-phase, slurry or bulk process equipment. Although the inorganic supports have been successfully industrialized, some inconvenient drawbacks calls for a new type of support to solve those problems. Porous organic polymers (POPs) have proved to be an excellent choice and have been considered as a versatile platform for the deployment of catalysts. The flexible design and synthesis approach provides POPs with high surface area and bulk density, excellent flowability, and various functionalities for desired catalysts performance. The POPs-based polyolefin catalysts obtained high polymerization activity and tailored molecule structure including molecular weight, molecular weight distribution, chemical composition distribution, stereoregularity, etc. due to the nature of the organic support.

Keywords:Porous organic polymers (POPs); Olefin polymerization; Metallocene catalyst; Ziegler-Natta catalyst
