摘要：
Monolithic specimens of the polymer-polymer blends of super high-molecular weight polyethylene and polymethyl methacrylate are synthesized by the polymerization of methyl methacrylate on powdered super high-molecular weight polyethylene in air and supercritical CO2. These systems are the blends of two linear polymers. The study of the tribological behavior of the composites at various sliding velocities has shown that the specimens synthesized in supercritical CO2 are advantageous in the friction coefficient and frictional temperature. The poorer tribological behavior of the composite produced in air is caused by the tribochemical processes resulting in counterbody wear.
