AB  - Waste from pneumatic wheels is one of the major environmental problems, and the 
      scientific community is looking for methods to recycle this type of waste. In 
      this paper, ground tire rubber particles (GTR) from disused tires have been mixed 
      with samples of low-density polyethylene (LDPE) and high-density polyethylene 
      (HDPE), and morphological tests have been performed using scanning electron 
      microscopy (SEM), as well as the dynamic electric analysis (DEA) dielectric 
      characterization technique using impedance spectroscopy. From this experience, 
      how GTR reinforcement influences polyethylene and what influence GTR particles 
      have on the branched polyethylene has been detected. For pure LDPE samples, a 
      Debye-type dielectric behavior is observed with an imperfect semicircle, which 
      depends on the temperature, as it shows differences for the samples at 30  degrees C and 
      120  degrees C, unlike the HDPE samples, which do not show such a trend. The behavior in 
      samples with Debye behavior is like an almost perfect dipole and is due to the 
      crystalline behavior of polyethylene at high temperature and without any 
      reinforcement. These have been obtained evidence that for branched PE (LPDE) the 
      Maxwell Wagner Sillars (MWS) effect is highly remarkable and that this happens 
      due to the intrachain polarization effect combined with MWS. This means that the 
      permittivity and conductivity at LDPE/50%GTR are high than LDPE/70%GTR. However, 
      it does not always occur that way with HDPE composites in which HDPE/70%GTR has 
      the highest values of permittivity and conductivity, due to the presence of 
      conductive fraction (Carbon Black-30%) in the GTR particles and their dielectric 
      behavior.
