Results of an investigation into the mechanical properties of polyethylene with small, no more than 3 wt.%, additions of a thermotropic liquid-crystalline polymer (LCP) are reported. Experimental data on the influence of LCP additions on the tensile stress–strain diagram, elastic modulus, long-term (up to a 1000-h) creep, and creep recovery after unloading of the specimens are obtained. The elastic properties of the materials are analyzed taking into account the effect of self-reinforcement owing to the formation of extended LCP inclusions. The results obtained are compared with experimental data. Analytical descriptions of the creep and creep recovery of the materials investigated are also presented
