Type: article
Abstract: Ziegler-Natta (Z-N) catalysts hold great significance in the industrial production of ultrahigh molecular weight polyethylene (UHMWPE), given that their outstanding efficacy, profound impact on the molecular weight (MW) of UHMWPE, and extensive industrial applications are highly conspicuous. However, the UHMWPE prepared by Z-N catalyst is usually highly entangled. Considering chain entanglement is essential for altering the processability and mechanical characteristics of nascent UHMWPE, the synthesis of disentangled UHMWPE (dis-UHMWPE) is essential for industrial scalability, therefore holding considerable practical importance. This review summarized recent progress in optimizing Z-N catalysts for the synthesis of dis-UHMWPE, providing a comprehensive overview of research advancements, clarifying polymerization settings, linking polymer structure and activity, and introducing design principles for polymerization techniques. Moreover, the overarching objective is to reveal the principles behind material preparation methods and potentiate the application prospects of UHMWPE materials, therein propelling the advancement of related fields.
