Abstract
The rheological properties of compositions based on HDPE with the addition of chalk concentrate and linear low-density polyethylene (LLDPE), as well as the thermal stability of the investigated compositions, were studied by capillary viscometry and DSC. It is shown that the introduction of chalk concentrate with chalk content of 80 wt.% into HDPE sharply reduced the compositions thermal stability and changed the compositions flow character. The addition of LLDPE to chalk-filled HDPE resulted in a decrease in the effective viscosity and an increase in the thermal stability of the compositions.
