There are stand waves. One oscillator produce 3 waves: 1 longitudinal and 2 transversal [1]. The “fast” quasitransversal ultrasonic (US) velocity V┴1 = 768 m/sec, shear module G = ρV┴12 = 578 MPa, quasilongitudinal US velocity V║ = 2485 m/sec, dynamical elastic module E = ρV║2 = 6,057 GPa, Puasson coefficient μ = 0,442, specific density polyethylene with low density high pressure (C2H4)n + 3% multiwalled carbon nanotubes (MCNT) ρ = 980,8 kg/m3 was determined from the oscilloscopegramma on fig. 1.

The window illustration of data treatment of quasitransversal elastic waves velocity measuring V┴ = 768 ± 10 m/sec and the oscilloscopegramma of impulses in nanocomposite polyethylene with low density high pressure (C2H4)n + 3% multiwalled carbon nanotubes by impulse-phase method at frequency f║ = 0,7 MGz.

The correlation between elastic module Е, pressure P and temperature Т may be presented az surface (“directional surface of elasticity body”) before and after satiation, which gives additional information about influence of the saturation of solution.
