Ultrahigh molecular weight polyethylene (UHMWPE) shows outstanding toughness, wear resistance and chemical inertness as a high performance polymer. However, extremely high entanglement degree results in high viscosity and processing difficulties, which greatly limits the applications. To address this issue, the new single-site Z-N catalysts have been used to regulate the growth and cohesion of molecular chains during the polymerization of ethylene in recent years, by which nascent UHMWPE with low entanglement degree and excellent processing capability can be obtained. With such UHMWPE nascent powder, different sintering temperatures (T_s) of 170, 190 and 220 °C were set, respectively, then a isothermal crystallization step with precise temperature control was added, and the effect of chain entanglement on the structures and properties of sintered UHMWPE was investigated. Through the tensile tests at 160 °C, it was confirmed that UHMWPE chains significantly reentangled when T_s = 220 °C, resulting in high degree of entanglement; while the initial low entanglement state can be sufficiently reserved when T_s = 170 °C, M_e reached 12.3 kg/mol. Therefore, the samples with distinct different entanglement states can be obtained. DSC results have shown that low entanglement degree was beneficial to the formation of crystal lamellae with higher melting temperature (up to 141 °C) and high crystallinity (up to 65%) through isothermal crystallization steps, which was close to the level of nascent UHMWPE powder. Moreover, it proved that the integrated mechanical performance of the product sintered at 170 °C was significantly improved. The yield strength was increased by up to 72%, the tensile strength by 139%, the elastic modulus by 162%, and the elongation at break by 36%, realizing simultaneously strengthening and toughening of sintered UHMWPE materials. This provides a new strategy for the high performance UHMWPE sintered products from the perspective of chain entanglement regulation.
