Popis:	Results of experimental investigation of the dynamic mechanical and relaxation properties of composition materials of the polyethylene/exfoliated-graphite system, where the exfoliated-graphite content is varied from 0 to 1 volume fraction in the — 180–80°C interval are presented. As an effective filler, exfoliated graphite is demonstrated to improve the elasticity of composition materials. The major influence exerted by spatial graphite-particle structures on the mechanical-relaxation processes that take place in polyethylene and composition materials is established. The data obtained are examined from positions of the percolation theory. Expressions of this theory are used to describe mathematically the variation in the dynamic shear modulus as a function of graphite content in a certain range of component concentrations and temperatures.
