Phase Diagrams of High-Density-Polyethylene—1,2,4,5-Tetrachlorobenzene Mixtures According to DSC Data

  • Published:
Fibre Chemistry Aims and scope

Direct experimental proof was obtained that 1,2,4,5-tetrachlorobenzene is soluble in solid and fused high-density polyethylene. It was shown that the shapes of semi-crystalline-polymer—low-molecularmass-crystalline-compound phase diagrams obtained using DSC were independent of whether the system was considered to be a mixture of two crystalline compounds or a liquid with a crystalline compound. In contrast with mixtures of low-molecular-mass crystalline compounds that form eutectic mixtures of strictly defined compositions, mixtures of the polymer and low-molecular-mass compound were characterized by a certain range of compositions in which both components crystallized simultaneously.

Notes

  1. It was shown [1] that such a delay was sufficient to obtain a homogeneous mixture. The validity of this conclusion was

    confirmed in our experiments by the fact that the crystallization exotherms of the mixtures after the first and second

    melting were identical.

  2. The lack of a second peak in thermograms of systems with w 2 > w 2B was noted [46, 8].
