AB  - The compositions based on bimodal high-density polyethylene (HDPE, copolymer of 
      ethylene with hexene-1) and in mixture with monomodal tercopolymer of ethylene 
      with butene-1/hexene-1 (LLDPE, low-density polyethylene) have been studied. Phase 
      equilibrium, thermodynamic parameters of interdiffusion in a wide range of 
      temperatures and ratios of co-components were identified by refractometry, 
      differential scanning calorimetry, optical laser interferometry, X-ray phase 
      analysis. The phase state diagrams of the HDPE-LLDPE systems were constructed. It 
      has been established that they belong to the class of state diagrams of "solid 
      crystal solutions with unrestricted mixing of components". The paired parameters 
      of the components interaction and their temperature dependences were calculated. 
      Thermodynamic compatibility of alpha-olefins in the region of melts and 
      crystallization of one of the components has been shown. The kinetics of 
      formation of interphase boundaries during crystallization of alpha-olefins has been 
      analyzed. The morphology of crystallized gradient diffusion zones has been 
      analyzed by optical polarization microscopy. The sizes of spherulites in 
      different areas of concentration profiles and values of interdiffusion 
      coefficients were determined.
