This study compares the isothermal crystallization kinetics of nascent less-entangled UHMWPE ( PE_30°C_60min , synthesized via 5F-BAOFI/MAO) with conventional highly entangled C-UHMWPE of similar molecular weight. Avrami kinetic and Lauritzen-Hoffman analysis revealed that chain entanglement density critically governs crystallization behavior. The less-entangled PE_30°C_60min demonstrated superior crystallizability, evidenced by more crystalline domains in longer crystallization times compared to C-UHMWPE. Lauritzen-Hoffman calculations quant...
